Thread: pulse amplitude modulation

dear friends


plz i need a usufull and simple design to the circuit (pulse amplitude modulation) and i hope if anybody help me to simulate it in orcad


appreciate your works



thanks a lot regards

so could you please give me a random valuse to these inputs

regards

V1 Starting voltage for pulse
V2 Second voltage for pulse
TD Time delay. Voltage will remain at V1 until this specified time.
TR Rise time. Time required to reach V2 from V1 (Rise time must not equal to zero).
TF Fall time. Time required for voltage to change from V2 to V1 (Again, fall
time must not be equal to zero).
PW Pulse width. Amount of time pulse remains at V2.
PER Period of pulse. How often pulse actually repeats itself
