A latch is a:
Monostable state device
Bistable state device
None of the above
In an SR Active High latch, if S = 1 and R = 0, the output will be:
Q = 0, Q̅ = 1
Q = 1, Q̅ = 0
Q = 1, Q̅ = 1
Q = 0, Q̅ = 0
What are the inputs that will cause the invalid state of an SR latch using NOR gates?
S = 1, R = 0
S = 0, R = 1
S = 1, R = 1
S = 0, R = 0
Select the following types of Flip flop :
(Answer can be more than 1)
JK Flip flop
DE Flip flop
SR Flip flop
TU Flip flop
The main difference between a latch and a flip-flop is :
(answer can be more than 1)
Latch is bistable device, while Flip flop in Monostable device
Flip Flop requires clock
Latch requires clock
Output of Flip flop changes depends on triggering clock
Advantages of D Flip flop :
(answer can be more than 1)
Simple Design With only one input , it’s easier to implement and less prone to input errors.
D Flip-Flops are commonly used to store bits in registers, shift registers, and counters.
Complex Design will cause the design has more gates
Multiple D Flip-Flops can be easily connected in series like shift registers.
1 bit enter into register per clock pulse, and shifted out 1 bit per clock pulse.
The following operation above, desribe a ________
Serial in Serial Out (SISO)
Serial in Parallel Out (SIPO)
Parallel in Serial Out (PISO)
Parallel in Parallel Out (PIPO)
The following Shift Register is :
SISO
SIPO
PISO
PIPO
The figure below shows the circuit of ________ where it is one of Shift Register application. Name the following :
Johnson Counter
Johnny Counter
Ring Counter
Pyramid Counter
Description :
It’s basically a shift register where the output of the last flip-flop is connected back to the input of the first.
Uses D-type flip-flops (typically)
Only one flip-flop is HIGH (1) at any time; all others are LOW (0).
Based on description above, choose the right counter
Johnson Counter
Ring counter
