# pulse amplitude modulation

1. ## 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

thanks a lot regards

my friend could you please give me a circuit diagram without IC's . i mean with components ( op Amp - R-L-C......)

thanks a lot

i use this design and i don't know what is the resoan

please check it and tell me the where is the problem ?

thanks

my advisor want the sample and hold circuit by using op-amp and JFET

8. ## Re: pulse amplitude modulation

can you make a simulation or just give the values for these components

regards

10. ## Re: pulse amplitude modulation

when i want to add pulse generator in ORCAD . there are many inputs i don't know what is the meaning of them whice are : V1-V2-TD-TR-TF_PW and PER ?

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

regards

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

12. ## Re: pulse amplitude modulation

could u plz give me the vaules of this design cuz my advisor want the PAM design by using sample ana hold ( and this design )

waiting ur response
