Assignment:
Question 1. When a square wave with a fundamental frequency of 2khz and amplitude 5v and comprised of up to five odd harmonic (each successive odd harmonic having half the amplitude of its predecessor) is passed though a standard telephone line of bandwidth of 4kHz it was found to be severely degraded. Explain why this happens and draw what may appear on a spectrum analyser and oscilloscope at the input and output of this system assuming there is no attenuation.
Question 2. A single pole low pass RC filter has component values 100 ohms and 0.1 uf. If a signal Vi = 5 Sin 6283 (t) is applied, calculate:
1) The peak output voltage
2) The phase angle
3) The propagation delay time.
Provide complete and step by step solution for the question and show calculations and use formulas.
