Operating characteristics of flip-flops


Q1: Describe the principles of operation of the following sequential logic devices:

a. D-type flip-flop
b. J-K flip-flop

Illustrate your answer by providing the combinational logic equivalent circuit of every device, the function (truth) table and the input, clock and output digital waveform.

Q2: Define and explain in detail the following operating characteristics of flip-flops and support your answers with illustrations of waveforms of the input and output digital signals:

a. Propagation Delay Time
b. Step-up time
c. Hold time

Support your answers with datasheets.

Q3: Using three JK flip flops and a digital clock, design a frequency divider digital circuit. Draw the output waveforms when an 800Hz signal of the output of the clock is applied to the clock input of the 1st flip flop. Explain the operation of the circuit.

Q4: Determine the output waveform in relation to the clock for QA, QB and QC in the following circuit and show the binary sequence represented by these waveforms
