Square-Law Demodulation A square-law demodulator will, under certain constraints on the amplitudes, demodulate an AM signal. Use the same square message from above and apply a square-law demodulator to the result. Try using different amplitudes for the information signals and observe the reconstructed signals. 13) What constraint did you have to apply to obtain an acceptable result? Explain why this constraint is necessary for square-law demodulators. Rectifier Detector 14) AM signals without overmodulation can be detected with a rectifier followed by a lowpass filter. On the other hand, a DSBSC cannot. Explore both with the signal from above. Envelope Detector Follow the block diagram to build an envelope detector. 15) How large of a constant did you need to add to the input signal s(t) to make the detected signal visually indistinguishable from the original? Does envelope detection work better for AM? Explain why.
