Double - Sideband Suppressed - Carrier (DSB - SC) Demodulation

Calculations & Observations




Fig.1 Demodulated DSB - SC wave.

The demodulated wave is shown in the green signal & the message signal of 2 kHz sine wave is shown in the blue signal in the Fig.1.



Fig.2 Frequency Spectrum of DSB - SC Demodulation.

In the Fig.2 , the frequency spectrum of DSB - SC Demodulated wave has a frequency component at 2083.03 Hz with corresponding Power component of 0.40. The THD is 2.56 % & SINAD is 24.17 dB.





Fig.3 Power Spectrum of DSB - SC Demodulated wave.

The Fig.3 i.e. the Power Spectrum of DSB - SC demodulated wave is obtained with the fundamental frequency detected is at 2083.01 Hz with corresponding magnitude of 0.40. The THD is 3.40% & SINAD is 23.13 dB.
