- 1whats the difference between synchronous and Asynchronous logic circuits* synchronous is a circuit that output changes state simultaneously with the clock input signals
*Asynchronous is a circuit that outputs do not change with the clock input which has a ripple effect. - 2explain the difference between a flipflop and a registerflipflops only store one bit whereas a register can store multiple bits and synchronise the outputs to the clock signal
registers are usually used as temporary storage in a processor as they are fast - 3What is clock-gating and why it should be avoided?clock gating is when gates are added to the clock signal.
it should be avoided as the clock gets delayed by adding gates which means flipflops in the system can receive the signals ad different times.
can damage synchronisation - 4draw a 2 bit J-k Counter
- 5define close loop voltage gainopen loop = (vout/v2-v1)
close loop = acl= vout/v1
