Question:

Assume a 1-Hz clock is applied to the seconds stage of the clock in Figure 10-17. The MOD-10 units of seconds counter’s terminal count (tc) output is shown in Figure 10-51. Draw a similar diagram showing the number of clock cycles between the tc output pulses of each of the following:

(a) Tens of seconds counter 

(b) Units of minutes counter 

(c) Tens of minutes counter


Figure 10-51


Terminal count (tc) 1 clock cycle (1 s) 10 clock cycles (Talk = 1 s)
