Steady State response of Averager: An analog averager is given by:
y(t) = 1/T (integral from t-T to t) of x(tao) d(tao)
(a) Let x(t) = u(t) u(t 1).Find the average signal y(t) using the above integral. Let T = 1. Carefully plot y(t).Verify your result by graphically computing the convolution of x(t) and the impulse response h(t) of the averager.
(b) To see the effect of T on the averager, consider the signal to be averaged to be x(t) = cos(2?t/T0)u(t). Select the smallest possible value of T in the averager so that the steady state response of the system y(t)as t will be 0.
(c) Use MATLAB to compute the output in part(b). Compute the output y(t) for 0 t 2 at intervals Ts = 0.001. Approximate the convolution signal integral using the function conv multiplied by Ts.
Looking at feedback and some Opamp problems, If the unity gain frequency is 5 MHz and the midband open-loop voltage gain is 200,000, what is the cutoff frequency?
A pulse width modulation (PWM) circuit works by varying the duty cycle of the square wave while keeping the period fixed.
What is the maximum allowable value Xmax of X? The system is built with X-Xmax. An engineer argues that the host on the sort side of the bridge can use a minimum frame length shorter than 512 bits if they are talking to other hosts on the same sid..
