I need the design in Multisim for attached problem....on paper is good enough that i can simulate in multisim..

THANK Y'all

 

Hello,

A ring-modulator is designed for Dual Sideband-Suppressed Carrier modulation.
Make it work that way.
Then see what happens when you give a DC offset on the modulation signal.

Now show what you have done.

I have come up with the following design so far in Multisim.....Can you please guide me about missing components ( diodes, summing amplifiers etc.)

Thanks

 

Hello,

The circuit you show has nothing to do with the ring-modulator:

Here is the original question:

I do not see any diodes and balanced transformers in your circuit.

Bertus

 

Exactly thats where I am stuck and needed help......Can you break it down for me.....I am being asked to modify a ring modulator to transmit AM and not jujst DSB-SC.

 

Hello,

Did you see my remarks in post #2?

Bertus

 

yes I did..... so you are saying I can construct a simple ring modualtor (for DSB-SC) and give it DC offset on modulation signal??

THANKS again

 

Hey!
We're in the same boat! Literally, I'm working on the same project!

 

I think your design should look a little more like this:


Let me know if you notice any issues with my design, or if you think of an oscillator that can be used to generate 2Vpp @ 10KHz
