"WebApr 29, 2024 · In the simplest case, a sine wave of unknown amplitude, in noise, is demodulated by multiplying by a reference sine wave of known amplitude, with the same frequency and phase as the noisy sine wave. Then the difference frequency is at DC, so the DC magnitude is proportional to the noisy sine wave’s amplitude. " - Incoherent demodulator matched filter

Web1. Learn how to use Matlab Simulink to design low-pass, high-pass, and band-pass filter. 2. Identify coherent and incoherent (envelope) demodulation for amplitude modulation. Equipment List: 1. PC with Matlab and Simulink Prelab: 1. Filter The Band pass filter (BPF) and the low pass filter (LPF) will be used extensively in this experiment In signal processing, a matched filter is obtained by correlating a known delayed signal, or template, with an unknown signal to detect the presence of the template in the unknown signal. This is equivalent to convolving the unknown signal with a conjugated time-reversed version of the template. The matched filter is the optimal linear filter for maximizing the signal-to-noise ratio (SNR) in the presence of additive stochastic noise.
