A modulated broadcast signal which has been modulated consists of a a) carrier signal. b) data signal. c) carrier and data signal. d) frequency and amplitude signal.
Homework Answers
Correct Answer: d) frequency and amplitude signal.
Explanation:
The modulating system is a process in the electronic and communication in which we change the properties of a carrier signal. The modulator performs the modulation and the demodulator performs the demodulation. The modem performs both modulation and demodulation.
In FM (Frequency Modulation), the frequency of the upcoming signal is modified.
In AM (Amplitude Modulation), the amplitude of the upcoming signal is modified.
In analog modulation, the frequency and the amplitude are the properties of a signal which can be modified.
