ELEG403 COMMUNICATIONS SYSTEMS ENGINEERING ASSIGNMENT #2 due Monday September 22 1. Adelay line and integrating circuit as shown below are one example of a “holding circuit” that was commonly used in radar work, semplad-data servo systems, and Pulse-modulation syetems. a} Tracing through the circuit step-by-step, determine the transfer function Hif} = VAC (1. b) Let u(t) be a rectangular pulsa of width + seconds, determine the output v, Ct}. i) — delay line > amplifier js wit} po y $86 t gain =ft Integrato—-» v,(t) 2. Using the eupemesition (linearity) and time-shift theorems for Fourier transforma, find the tanaform of the signal shown below.
