a. How many pulses are generated in each second?
1000 pulses
b. What is the period of each pulse?
1/10MHz = 100ns
c. Draw one clock cycle with duty cycle of 50%. Indicate ALL the rising and falling edges.
Referring to the circuit:
d. How many flip-flops are required to design the above MOD-36 counter?
Six Flip-Flops
e. What is the counting sequence for this counter? Starting from zero state, indicate the first 5 and
last five states.
First five states: 0, 1, 2, 3, 4 …. Last five states: 31, 32, 33, 34, 35
f.
Assuming the count starts from zero, what will be the counter’s state after the 50th clock pulse?
14
g. What is the frequency at the output of the last flip-flop, when the input frequency is 10 MHz.
312,500Hz
