Therefore, the output waveform frequency of FF3 is f/16 and the time period is T=1/frequency=16/f. Since the time period of the last flip-flop (FF3) is 64 microseconds, T=16/f=64 x 10 -6, Then clock frequency of a 4-bit ripple counter is f=16/ (64 x 10 -6) …

Webb15 nov. 2008 · I am designing a flip flop circuit to count form 1 to 3 in binary and it is not allowed to ever be at 0 in binary. This means I have to use the preset and clear pins on the flip flops. I was given a suggestion in my lab manual for these pins, but it is very vague and I am not sure how to do it. The circuit can start in binary 01, 10, or 11. WebbEngineering Electrical Engineering 16. The following serial data are applied to the flip-flop through the AND gates as indicated in Figure 7-85. Determine the resulting serial data that appear on the Q output. There is one clock pulse for each bit time. Assume that Q is initially 0 and that PRE and CLR are HIGH. Right- most bits are applied first. Webb15 juli 2014 · Most flip-flops have other inputs that are asynchronous, meaning they affect the output independent of the clock.

WebbIf the input to the flip-flop has a Schmitt trigger design, you can use a simple R-C divider across the rails. Connect the reset line to the center of the divider. If you need a high value for reset and a low for operation, connect the resistor to ground and the cap to +Vcc. It's the reverse for opposite logic.
