Extracted text: Q4/ If figure (1) is the spectrum of the periodic signal answer the following for one period of this signal in time domain: - fkHz 12.5 Fig. (1) 7- If the L (even parity) error detection system are used, calculate the transmitted data and the required bandwidth. 8- If the V (even parity) error detection system are used, calculate the transmitted data and the required bandwidth. 9- If the L&V (even parity) error detection system are used, calculate the transmitted data and the required bandwidth. 10- If CRC error detection system are used which detect 8 error with 100% percent, state the polynomial and calculate the required bandwidth. rn N -
