A single corresponding to a 10-bit character is to be transmitted by a source station operating at bit rate of 10 kbps. Assuming that the signal will be transmitted over communication medium having a cut-off frequency of 7 kHz. The number of signal harmonics that will pass through the communication channel without being suppressed is: (Show your calculation) 5 6 7 9

Solution

Answer is 7

Signal will be sent effectively without suppression with in the channel band width

Channel band width is 7, so up to 7k Hz, signal transmitted with out any supression
