Check each statement that is true.
Question 2 options:
Check each statement that is true. Slaving the transmitter and receiver to a master timing source is a method of timing synchronization, however, it has a high implementation cost. Transmitting a separate synchronizing (pilot) signal uses part of the channel capacity for the pilot signal. Self-synchronization using only the transmitted data is not feasible for any type of digital modulation. ASK is also called On-Off Keying because the signal is either transmitted (On) or not transmitted (Off). ASK is like analog FM with a square wave modulating signal. FSK requires more bandwidth than ASK or PSK because it transmits on two different frequencies to represent the two symbols. Binary PSK looks like a digital DSB-SC signal and provides the best noise immunity. PSK provides the best noise immunity and can be non-coherently detected. PSK and FSK both use the same bandwidth for the same R_b. ASK, FSK, and DPSK can all be non-coherently detected.Explanation / Answer
Slaving the transmitter and receiver to a master timing source is methode of timing synchronization, however, it has a high implementation cost [TRUE]
Transmitting a separate synchronizing (pilot) signal uses part of the channel capacity for the pilot signal [FLASE]
Self sychronization using only the transmitted data is not feasible for any type of digital modulation[TRUE]
ASK is also called on-off keying because the signal is either transmitted(on) or not transmitted(off)[TRUE]
ASK is like analog FM with a square wave modulating signal[FLASE]
FSK requires more bandwidth than ASK or PSK because it transmits on two different frequenices to represent the two symbols[TRUE]
Binary PSK looks like a digital DSB-SC signal and provides the best noise immunity[TRUE]
PSK provides is best noise immunity and can be non-coherently detected[TRUE]
PSK and FSK both use the same banwitdth for the same rb[FLASE] because both different bandwidth [bandwidth is less compare to FSK]
ASK, FSK, AND DPSK can all be non-choerently detected[TRUE] because more effetcted by noise
