Question

3. a. b. Apply the input waveforms (A,B,&C) of the following figure to a NOR gate, & draw the output waveform. Repeat with C held permanently LOW. Repeat with C held HIGH. 10

Answer 1

. When the input waveforms will be applied to a Nor gate, then the output wave form will be at the logic high of all the o input wave forms are at logic low and if atleast one input wave form is at logic high then the output waveform will be at the logic lows AVT B OUTPUT - wow.com pic-1 I when c permanently held low, then the ym will look like same as pic-1 input and output except the waveform c. Art - (at logic Lan ove when like prona c held high, then the input and output waveform will look . (at logic HIGH) culput wowo (with Col, output - wareform=0 at all times) Summary: we know that oulput of a Nor gate is tbtc when the inputs are A, B, C, so if atleast one input is 1 , then the Nor gate will go on to produce output o and it all the inputs are o, then only Nor gate output will be 1.
