Hey all, I'm trying to build a circuit using flip flops that passes data in series using multisim. My problem is with the clock. I know that data isnt moved until a clock pluse comes along. My problem is that what exactly is the source of this (clock) pulse. Could it be a voltage source and a... Simulation and Model‑Based Design.
