1a) (2 pts) A 8 bit ripple counter has a 2.56 Khz clock signal applied What is the Mod number of this counter? 1b) (2 pts) What will be the frequency at the MSB output? 2) (3 pts) A 6 bit ripple counter is driven by a 60 Mhz clock. Each flip flop has tpd- 25 ns. What maximum clock frequency can be used with this counter? 3a) (7 pts) Draw a Mod 7, synchronous, negative edge triggered, up counter 3b) (5 pts) Draw the waveform diagram for this counter for 9 pulses 4) (3 pts) Refer to Fig. 7-75a. If the flip-flops are loaded with Q3-1,02-1 Q1-0, and 00-1, then what will the contents of those flip-flops be after three clock pulses. D Q D 03 D O2 CLK CLK CLK CLOCK 7-75a)
