Question

Explain how you could transmit two independent base-band information signals by using SSB on a common carrier frequency.

Answer 1

Answer:

Using Hilbert Transformation, we can transmit two independent base-band information signals by using SSB on a common-carrier frequency.

Explanation:

• In SSB modulators, we pre-process a real signal  by Hilbert Transform filter to form another real signal
• The signal has the same spectral amplitude but has 90° phase shift at each frequency relative to its input signal.
• The ordered pair gets almost all of its negative components cancelled
• thus, with the use of Hilbert Transformation, we can transmit two independent base-band information signals by using SSB on a common carrier frequency.
