The synchronous detection method of DSB-SC signals involves several steps. Here is a step-by-step explanation:

1. First, the DSB-SC (Double Sideband Suppressed Carrier) signal is received by the receiver.

2. The receiver then generates a local oscillator signal that has the same frequency and phase as the carrier signal that was suppressed in the transmitter.

3. The received DSB-SC signal is multiplied or mixed with the local oscillator signal. This process is known as synchronous detection.

4. The multiplication or mixing process results in two output signals: the sum frequency and the difference frequency.

5. The sum frequency component is filtered out, as it contains unwanted noise and interference.

6. The remaining difference frequency component is then amplified and passed through a low-pass filter to remove any high-frequency noise.

7. The filtered signal is then demodulated to recover the original baseband signal.

8. Finally, the demodulated baseband signal is amplified and processed further for any required applications or purposes.

In summary, the synchronous detection method of DSB-SC signals involves generating a local oscillator signal that matches the suppressed carrier frequency, multiplying or mixing it with the received signal, filtering out unwanted frequencies, and demodulating the resulting signal to recover the original baseband signal.
