Flip-flops:

a) Make a asyncronous MOD 12 flip-flop up counter circuit

b) Make a syncronous MOD 14 flip-flop up counter circuit

c) Each flip-flop has the same propagation delay, which is 10ms.
Calculate the maximum clock frequency of the circuit in questions
(a) and (b)

a) for minimum clock of mod 12 counter synchronous :

Take path R2 to R3(q2 to q3)

Tmin>= 10msec + (AND+OR) delay +setup

For minimum clock of mod 12 asynchronous counter

Tmin >= 10msec+setup

Any doubt comment me thank you

Design a decoder counter MOD '10' that counts from 0-9 using 4
flip flops and a NAND gate.

Design a mod 5 counter as a
(a) synchronous circuit
(b) asynchronous circuit

Design a sequential circuit with 2 JK flip-flops A and B, and 2 inputs, E and x. the design must adhere to the following requirements: If E = 0, the circuit remains in the same state regardless of the value of x. When E = 1 and x = 1, the circuit goes through the state transitions from 00 to 01 to 10 to 11 back to 00 and repeats. When E = 1 and x = 0, the circuit goes through the...

flops: a) D-FF (Active edge is high to low) b) SR-FF (Active edge
is high to low) c) Use of output of circuit in part (b) and minimum
number of logic gates for getting the Countdown counter in Aiken
code

What is a ripple counter? How is it constructed using D
flip-flops?

A sequential circuit has two JK flip-flops A and B, two inputs r and y, and one output z. The flip-flop input equations and circuit output equation are \(\begin{aligned} J_{A} &=A^{\prime} x+B^{\prime} y & K_{A}=B x^{\prime} y^{\prime} \\ J_{B} &=A^{\prime} x y & K_{B}=A^{\prime}+B^{\prime} x \\ z &=A^{\prime} x^{\prime}+B^{\prime} y^{\prime} & \end{aligned}\)(a) Derive the simplified state equations for A and B. (b) Tabulate the state table. (c) Draw the state diagram of the çircuit.

Implement the synchronous 2-bit Up/Down counter with saturation
at the end states. The flip-flop outputs Q1, Q0 serve as the
outputs of the counter. The counting direction is set with mode
control input M. With M =1 the flip-flop outputs follow the
incrementing binary sequence starting from a current state with
saturation at state 11 as shown in the following example: 00->
01-> 10-> 11-> 11-> 11... With M =0 the outputs follow
the decrementing binary sequence from a current...
