Is master-slave edge-triggered?

A D flip flop takes only a single input, the D (data) input. The masterslave configuration has the advantage of being edge-triggered, making it easier to use in larger circuits, since the inputs to a flipflop often depend on the state of its output.

How to Slave a Laptop Hard Drive

Q. What is a slave PC?

A slave is a computer or peripheral device that operates under the control of another computer peripheral. … The slave setting sets a drive as secondary and allows for two devices to be attached to a single IDE/ATAPI connection.

  1. Shut down your laptop and remove the power cord. …
  2. Grasp the hard drive by the front bezel and pull it out of the laptop. …
  3. Connect the USB cord from the laptop drive enclosure to a free USB port on a working desktop or laptop. …
  4. Log on to your working computer and right-click the “Start” button.

Q. What is master slave flip flop?

The MasterSlave FlipFlop is basically a combination of two JK flip-flops connected together in a series configuration. Out of these, one acts as the “master” and the other as a “slave”./span>

Q. What is the advantage of master-slave flip flop?

The master section of this flip-flop is like an edgetriggered device. The slave section becomes a pulse-triggered device to produce a postponed output on the falling edge of the clock pulse. The logic symbols of S-R, J-K and D data lock-out flip-flops are shown below.

Q. Why JK flip flop is used?

A J-K flipflop is nothing more than an S-R flipflop with an added layer of feedback. This feedback selectively enables one of the two set/reset inputs so that they cannot both carry an active signal to the multivibrator circuit, thus eliminating the invalid condition.

Q. How does JK flip flop work?

The sequential operation of the JK flip flop is exactly the same as for the previous SR flipflop with the same “Set” and “Reset” inputs. … Due to this additional clocked input, a JK flipflop has four possible input combinations, “logic 1”, “logic 0”, “no change” and “toggle”.

Q. Where is JK flip flop used?

JK Flip Flop is a universal flipflop that makes the circuit toggle between two states and is widely used in shift registers, counters, PWM and computer applications. Before we nail down the details of JK Flip Flop, we must know what is Flip Flop./span>

Q. What is the drawback of JK flip flop?

JK flipflop has a drawback of timing problem known as “RACE”. The condition of RACE arises if the output Q changes its state before the timing pulse of the clock input has time to go in OFF state. The timing pulse period (T) should be kept as short as possible to avoid the problem of timing.

Q. What is the difference between JK flip flop and T flip flop?

This is a much simpler version of the J-K flip flop. Both the J and K inputs are connected together and thus are also called a single input J-K flip flop. When clock pulse is given to the flip flop, the output begins to toggle.

Q. What is T type flip flop?

The T or “toggleflipflop changes its output on each clock edge, giving an output which is half the frequency of the signal to the T input. It is useful for constructing binary counters, frequency dividers, and general binary addition devices. It can be made from a J-K flipflop by tying both of its inputs high.

Q. What does flip flop do?

A flipflop is a device which stores a single bit (binary digit) of data; one of its two states represents a “one” and the other represents a “zero”. Such data storage can be used for storage of state, and such a circuit is described as sequential logic in electronics.

Q. What is set reset flip flop?

SetReset FlipFlop Operations. The set/reset type flipflop is triggered to a high state at Q by the “set” signal and holds that value until reset to low by a signal at the Reset input. This can be implemented as a NAND gate latch or a NOR gate latch and as a clocked version. … The J-K flipflop gets around that problem …

Q. What is difference between latch and flipflop?

The difference between a latch and a flip-flop is that a latch is level-triggered (outputs can change as soon as the inputs changes) and Flip-Flop is edge-triggered (only changes state when a control signal goes from high to low or low to high)./span>

Q. How many types of latches are?

four

Q. Where are latches used?

Application of Latches

  • Generally, latches are used to keep the conditions of the bits to encode binary numbers.
  • Latches are single bit storage elements which are widely used in computing as well as data storage.
  • Latches are used in the circuits like power gating & clock as a storage device.

Q. What are the types of flip flop?

There are basically four different types of flip flops and these are:

  • Set-Reset (SR) flipflop or Latch.
  • JK flipflop.
  • D (Data or Delay) flipflop.
  • T (Toggle) flipflop.

Q. Why latches are called memory devices?

Why latches are called memory devices? Explanation: Latches can be memory devices, and can store one bit of data for as long as the device is powered. Once device is turned off, the memory gets refreshed. Explanation: A latch has two stable states, following the principle of Bistable Multivibrator.

Q. Why recirculating latches are called quasi static?

This latch is called quasistatic because the latched data will vanish if clocks are stopped, but as long as the clocks are running, the data will be recirculated and refreshed, i.e. it is said to be static in one phase.

Q. Why XOR gate is called an inverter?

Why XOR gate is called an inverter? Explanation: The XOR (Exclusive Or) gate has a true output when the two inputs are different. When one input is true, the output is the inversion of the other. When one input is false, the output is the non-inversion of the other.

Q. What is the hold condition of a flip flop?

Explanation: The hold condition in a flipflop is obtained when both of the inputs are LOW. It is the No Change State or Memory Storage state if a flipflop. Explanation: If S=0, R=1, the flip flop is at reset condition. Then at S=0, R=0, there is no change.

Q. Is a register a flip flop?

A flipflop is said to be transparent when the Q output responds immediately to a change on the input. A register is a group of flipflops used to store a binary word. One flipflop is needed for each bit in the data word. AND gates can be used to “strobe” or enable data gated into a register.

Q. Which flip flop is used in counters?

74LS73 Toggle Flip Flop Since there are only two states, a T-type flipflop is ideal for use in frequency division and binary counter design. Binary ripple counters can be built using “Toggle” or “T-type flipflops” by connecting the output of one to the clock input of the next.

Q. What advantage does a JK flip flop have over an RS flip flop?

What advantage does a J-K flipflop have over an R-S flipflop? It has fewer gates. It has no invalid states.

Q. What is the difference between 7490 and 7492?

Explanation: From the properties of both ICs, we have 7490 is a MOD-10, 7492 is a MOD-12. Thus, IC-7490 can have maximum 10 states, while IC-7492 can have maximum 12 states.

Q. What is one disadvantage of an RS flip flop?

The one major disadvantage of the s-r flip flop is that in the condition when the clock is triggered the inputs become high which is an undesirable condition because it causes invalid input ,the condition in which you can’t predict the output./span>

Q. Which of the following is correct for ad flip flop?

Which of the following is correct for a gated D flipflop? Explanation: If clock is high then the D flipflop operate and we know that input is equals to output in case of D flipflop. It stores the value on the data line. Explanation: Latch is nothing but flip flop which holds the o/p or i/p state.
