Modulation and Demodulation are important aspects in communication. The paper will give the results of modulation and demodulation circuit using analog multiplier. These multiplier works in four ...

He’s broken down the modulation and demodulation circuits into their basic op-amp stages with examples of what the signal should look like on a scope after each stage. That’s the beauty here.

The AFE circuit uses Hanning-coordinate rotation digital computer-discrete Fourier transform (Hanning-CORDIC-DFT) algorithm for demodulation. The data judgment algorithm controls the disconnection of ...
