1.	By applying cos(2πft), BPSK signal is equivalent to ________(a) Double sideband suppressed carrier amplitude modulated waveform(b) Single sideband suppressed carrier amplitude modulated waveform(c) Frequency modulated waveform(d) SSB amplitude waveformThis question was addressed to me in an interview.I want to ask this question from Linear Modulation Techniques topic in portion Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» The correct option is (a) Double sideband SUPPRESSED carrier amplitude modulated waveform To elaborate: The BPSK signal is EQUIVALENT to a double sideband suppressed carrier amplitude modulated waveform, where cos(2πft) is applied as the carrier. Hence, a BPSK signal can be GENERATED using a balanced MODULATOR.
