1.	In India, the subcarrier frequency for transmission of color difference signals in television is approximately ________(a) 10.47 MHZ(b) 5.4 MHZ(c) 7.67 MHZ(d) 1.3 MHZThis question was posed to me by my college director while I was bunking the class.My question is based upon Hilbert Transform topic in portion Double Sideband Suppressed Carrier Modulation of Analog Communications
Answer» The correct answer is (d) 1.3 MHZ To elaborate: A carrier wave is a signal with a high FREQUENCY which is modulated for transmitting the INFORMATION signal. A subcarrier is a sideband of the carrier wave, which is also modulated to SEND additional information. In INDIA, the subcarrier frequency for transmission of color DIFFERENCE signals in television is approximately 1.3MHz.
