Question

Select the correct statement(s) regarding frequency modulation (FM). a. baseband amplitude changes (information) are captured as carrier wave frequency changes b. a device such as the voltage controlled oscillator (VCO) is required to convert signal amplitude changes to changes in frequency c. the more the carrier frequency is allowed to change (i.e., Δf), the greater the bandwidth as seen in the frequency domain d. all of the above are correct statements

Answer 1

All of the above statement are correct statement.

Step-by-step explanation

• Base-Band amplitude changes are captured as carrier wave wave frequency changes. In order to convert signal amplitude changes to changes in frequency, we need a device like VCO.

• The bandwidth in the frequency domain increases with the change in carrier frequency.
