Experiment 4 - The Asynchronous Inputs
For shift register the reset input is especially important.
With this input, you are put in a position to put
the entire shift register to "0" (or "1").
For the RESET input you use
the asynchronous inputs of the
SET (S)- set the output
Q = 1
RESET (R)- set the output
Q = 0
It is important that they are asynchronous inputs.
A D-flip-flop can be switched through the
independent of the clock signal
Circuit diagram asynchronous inputs D-flip flops.
Circuit asynchronous inputs D-flip flops.
In the next experiment you integrate the
RESET input into the 4-bit shift register...
