Let y1(t)=y2(t)=t-1 over 0<=t<=1. Notice, this statement does not require y1(t)=y2(t) for all t.
A) Define y1(t) as an even, periodic signal with period T1=2. Determine it's power.
B) Design an odd, periodic signal y2(t) with period T2=3 and power equal to unity.
C)Create a complex-valued function y3(t)=y1(t)+j*y2(t). Is this periodic? If yes, find the period T3, if not explain why
D)Determine the power of y3(t) defined in C). The power of a complex-valued function z(t) is P=lim(T goes to infinity) 1/T integral(z(tau)z*(tau) dtau from -T/2 to T/2
What are the design implications for the location and positioning of solar cells? Explain why the use of solar cells might be more appropriate in some regions of the country.
For the depletion-load amplifier, let W1=80microm, L1=4micrometers, W2=8 micrometers and L2=32 micrometers. If the body-effect parameter X=0.2, find the voltage gain neglecting the effect on ro.
A painter is standing on a work platform that is 27 feet above ground level. For fall protection, the worker''s safety harness D-ring is attached to a 12-foot shock absorbing lanyard that is securely fastened to the structure at a point 40 feet above..
At the receiver, demodulate the double side band signal S(t) = [cos(90*pi*t) + cos(120*pi*t)] * [cos(400*pi*t)], with the local carrier cos(400*pi*t). Design a low pass filter to suppress the carrier and plot the amplitude spectrum of S(t)
