2. A fundamental signal of s(t) = 5x10 cos(2000) suffers a phase shift of +(1/4) radian when it is transmitted over a 2Km wireless link. Determine the amplitude and frequency (in KHz) of this signal [2 marks) Based on the scales given in FIGURE Q1, sketch on the same diagram two cycles of the signal waveform at the transmitter and at the receiver respectively. millisecond H FIGURE Q1 15 marks)
