WebTranscribed Image Text: Suppose that the modulating (message) signal is m (t) = 0.5sin (20πt) and we are performing double sideband suppressed carrier (DSB-SC) modulation using a cosine carrier with frequency wc = 200π rad/s. a. Write the mathematical expression of the modulating (message) signal spectrum M (w) and sketch it (label the axes … WebLab 5.4 Demodulate the DSB signal using Coherent Detection 1. Set up the demodulation circuit with using the second AD534 as shown in Figure 4. This demodulator, which performs coherent demodulation, can demodulate both DSB-LC and DSB-SC. 2. Observe the output of the demodulator and plot the demodulated signal in the time and …
Web9.4 SNR in DSB-SC The modulated DSB-SC signal at the transmitter: θis a uniform random variable in [0, 2π], but is fixed during the transmission (The reason for including θis that the time origins of m(t) and cos(2 πfct) are independent). s(t) =A c m(t)cos(2π c f t +θ) 10 A linear DSB-SC receiver using coherent demodulation: http://ecelabs.njit.edu/ece489v2/Lab1.php
