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

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

More examples with JFET

please can you make the simulation with RC or JFET wit the values
 

please can you make the simulation with RC or JFET wit the values

JFET based PAM Circuit




JFET-BFW10
Resistor -100k
Signal-100Hz 5vpp,Sine ,control -1000Hz -5Vp Pulse
 




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
 

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

regards

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

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


regards
 

nothing works with me


plz another examples and easy to build it !!!
