Hello guys,
I am newbie here.
Sorry I got a question regarding to modulation.
Please take a look at the below PDF which is an AM DSB modulator out of 4066!
The Two questions which arrive to me are:
1. Is this circuit actually reliable as a DSB modulator?? For instance, is it able to honestly work instead of an MC1495 AM modulator?
2. It uses a band pass filter (I am not sure why we need it to remove unwanted upper and lower frequencies?), How to calculate the bandwidth for it? Say I have a modulating signal of 4kHz and a carrier signal of say 400kHz, How do I calculate the best order filter for the said modulator?
Thanks a bunch.
