This project was dedicated to make amplitude modulation on a RZ signal. We studied the whole circuitry, made the
|
|
electronic schemes and calculated every component value to make everything work.
|
|
We used an NE-555 to generate an NRZ signal, then used a programmable circuit to convert it to an RZ signal,
|
|
then used a Wien bridge oscillator to generate a carrier sine that we multiplied to the RZ signal to modulate it.
|
|
After modulation, we made a synchronous demodulation using the generated carrier, a multiplier and a low-pass filter.

This was complicated. We had to do a lot of calculus and brainstorming,
|
|
deduce spectral densities of the various signals,
|
|
without doing any circuitry.
|
|
But still it was fun and interesting to learn.
