Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe type of AM signal that is generated using only a balanced modulator and/or ring modulator without using any additional processing is Double Sideband Suppressed Carrier (DSB-SC).
Explanation:
-
Balanced Modulator and Ring Modulator: These circuits are specifically designed to perform multiplication of the message signal with the carrier signal. A key characteristic of both balanced and ring modulators is their ability to suppress the carrier frequency at the output.
-
DSB-SC Generation: When a message signal modulates a carrier wave using a balanced or ring modulator, the output signal consists of two sidebands (upper sideband and lower sideband) and has the carrier frequency component completely or largely suppressed. This direct output is precisely a Double Sideband Suppressed Carrier (DSB-SC) signal.
-
Other Modulation Types:
-
Single Sideband Suppressed Carrier (SSB-SC) and Vestigial Sideband Modulation (VSB) typically require additional filtering stages after DSB-SC generation to remove one entire sideband (for SSB-SC) or a portion of it (for VSB).
-
Wideband FM Signal is a type of frequency modulation, not amplitude modulation, and uses different modulation techniques.
