Question

(a) The waveform of a pulse wave is illustrated below. The pulse duration T = 1msand the period T = 4 ms.

What is the fundamental angular frequency? Show the expression of the n-thharmonic frequency component of the pulse wave. Sketch the spectral distribution of the pulse wave and label the frequency of zero crossing. (b) A digital coded transmission system uses a cyclic code generator of x³ + x² +x5 + x³ + x + 1 for error detection. The digital data to be encoded is 10001011 1001, which is 12-bit temperature data provided by an analogue to digital(ADC) converter. Using the generator determine the transmitted cyclic code.
