1. Answer the following questions related to Lecture 19 on registers and counters: . Consider the serial adder on slide 10. Let registers A and B be bit shift registers, and assume that the Shift Control input is set to the "shift right" mode. Suppose that the initial contents of registers A, B, and the D flip flop are A-0110, B-0011, and Q-0. What are the contents of A, B and the D lip flop.. - after one clock edge....
A pulse-generating circuit generates eight repetitive pulses as shown in the figure. Implement the pulse-generating circuit using the counter circuits listed and a minimum of gate logic. Use J-K flip-flops for the counters that trigger on the falling edge of a clock that has a frequency eight times the frequency of one of the pulses. The pulses must be free of glitches; explain any restrictions on the propagation delays of gates and flip-flops so that the pulses will be glitch...

Consider the circuit in Figure 1. It is a 4-bit (QQ2Q3) synchronous counter which uses four T-type flip-flops. The counter increases its value on each positive edge of the clock if the Enable signal is asserted. The counter is reset to 0 by setting the Clear signal low. You are to implement an 8-bit counter of this type Enable T Q Clock Clear Figure 1. 4-bit synchronous counter (but you need to implement 8-bit counter in this lab) Specific notes:...
