Q: If the bandwidth of a baseband signal is 10 Hz, what will the bandwidth of the signal be if it is…

A: We need to find out the bandwidth for given signal .

Frequency Modulation

Frequency modulation is a method or process of encoding the data of a specific signal (analog or digital) by modulating the carrier wave frequency according to the frequency of the modulated signal. Modulated signals are nothing more than information or data that should be conveyed after being converted into electronic signals.
