An oscillator by definition is a source (no input) that generates a sinusoid of a certain frequency ω0. Therefore an oscillator is a system whose zero-input response is a sinusoid of the desired frequency. Find the transfer function of a digital oscillator to oscillate at 10 kHz by the methods described in parts a and b. In both methods select T so that there are 10 samples in each cycle of the sinusoid
a. Choose H [z] directly so that its zero-input response is a discrete-time sinusoid of frequency Ω = ωT corresponding to 10 kHz.
b. Choose Ha(s) whose zero-input response is an analog sinusoid of 10 kHz. Now use the impulse invariance method to determine H[z].
c. Show a canonical realization of the oscillator.

Assume the flow to be laminar. Find the pressure rise and efficiency as a function of the flow rate per unit depth.
A 400-kV transmission line has a hot-weather power rating of1400 MVA. If the transmission line is operating in cold weather, itis rated for 2200 MVA (at 400 kV). The transmission line is undercold weather conditions, and the operating voltage is 3..
Derive a minimum cost realization of the four varible function that is equal to 1 if exactly two or exactly three of its variables are equal to 1; otherwise it is equal to 0. find the minimum cost SOP and POS forms for the function f(x1,x2,x3,x4)= ..
Phase a of a 3-phase stator at the instant of carrying maximum current has 60 amperesconductors in the phase belt. Sketch the mmf wave of the phase when the slots/pole/phase are 1, 2, 3, 4 and 5 respectively. Comment upon the change in shape of mm..
Suppose that the input voltage to an amplifier has a peak amplitude of 100mVand contains components with frequencies ranging from 1 to 10 kHz. We want the output voltage waveform to be nearly identical to that of the input except with larger ampli..
Pendulum. Find the frequency of oscillation of a pendulum of length L (Fig. 42), neglecting air resistance and the weight of the rod, and assuming θ to be so small that practically equals θ.
Production cost refers to prime cost plus 1. factory, administration and sales overheads 2. factory overheads 3. factory and administration overheads 4. factory, administration, sales overheads and profit
