True or false
1) In asynchronous counters made of JK flip-flops, the main clock signal is fed into the CLK input of
the most significant flip-flop.
2) The propagation delay in individual stages of an asynchronous counter is cumulative
3) The Q output from a JK flip-flop toggles on each clock input cycle as long as J = K = 1.
4) Generally speaking, a synchronous counter requires more circuitry than a comparable
asynchronous counter.
5) A counter that counts from 0000 to 1111 is called a MOD-16 counter.
6) A MOD-4 counter with an input clock frequency of 1500 Hz has an output frequency of 375 Hz.
7) A MOD-10 counter is also referred to as a decade counter.
8) MOD number = 2^n, where n = number of flip-flops.
9) A MOD-10 counter resets at 1010, thereby never actually reaching 10.
10) One potential problem with asynchronous counters is that the overall propagation delay increases with each added flip-flop.
11) Synchronous counters require less circuitry than asynchronous counters.
12) The MOD number of a Johnson counter always equals one-half the number of flip-flops in the counter.
13) All flip-flops change states at the same time in an asynchronous counter.
14) A MOD-5 counter would count to a maximum of 101 and then clear to recycle.
15) Typically, four flip-flops are required for a MOD-60 counter.
