WebBuffers — A buffer is a non-inverting amplifier that has an output drive capacity that is far greater than its input drive requirement, i.e., it has a high fan-out and gives a logic 1 output for a logic 1 input, etc. Inverters — An inverter (also known as a NOT gate) is a high fan-out amplifier that gives a logic 1 output for a logic 0 ... WebSo for example, if the rise delay is more than the fall delay than the output of clock pulse width will have less width for high level than the input clock pulse. The difference b/w rise and fall time is: 0.007. High pulse: 0.5-0.006=0.494. Low pulse: 0.5+0.006=0.506. We can understand it with an example:-. high school yearbooks 1974
