Digital Design - Chap. 7 , Chap. 10

7.1 Latches

sequential circuit:

a digital circuit whose output depends not only on the present combination of inputs, but also on the history of the circuit.


latch:

a sequential circuit with two inputs called SET and RESET, which make the latch store a logic 0 (reset) or 1 (set) until actively changed.


Chap. 10 - Summary

1. a state machine is a synchronous sequential circuit with a memory section (flip-flops) to hold the present state of the machine and a control section (gates) to determine the machine's next state.
