Where RC = 1/w.arrow_forward1.Select the correct statement(s) regarding frequency modulation (FM) bandwidth. a. the more the carrier frequency is allowed to change frequencies (Δf), the smaller the modulated signal bandwidth b. the larger the FM index, β, the larger the modulated signal bandwidth c. as you increase kvco, you decrease modulated signal bandwidth d. all statements are correct 2. Select the correct statement(s) regarding baseband signal modulation. a. with modulation, a baseband signal can be moved to a higher frequency thus preventing baseband signal interference b. modulation techniques are only required for analog information signals, since digital signals are represented by discrete logical values of “1” and “0” c. modulation eliminates the baseband signal’s frequency bandwidth, thus enabling greater efficiencies when transmitting a modulated carrier signal d. all statements are correct 3.
