Raised cosine (RC) pulses may be used in preference to sinc() pulses becauseQuestion 3Select one:RC pulses can be used for multilevel signallingRC pulses concentrate more signal energy in a smaller frequency range It means that sampling is less sensitive to timing errorsRC pulses have a narrower frequency bandwidth
Solution
Raised cosine (RC) pulses are often preferred over sinc() pulses for several reasons:
-
Multilevel Signalling: RC pulses can be used for multilevel signalling. This means that they can represent more than one bit of data per symbol, making them more efficient in terms of data rate.
-
Signal Energy Concentration: RC pulses concentrate more signal energy in a smaller frequency range. This makes them more resistant to noise and interference, improving the quality of the signal.
-
Less Sensitive to Timing Errors: The shape of the RC pulse means that sampling is less sensitive to timing errors. This makes it easier to accurately recover the original signal at the receiver.
-
Narrower Frequency Bandwidth: RC pulses have a narrower frequency bandwidth than sinc() pulses. This makes them more bandwidth-efficient, which is a crucial factor in many communication systems.
