Write an m-file "sampling.m", which will take as an input: a signal and a sampling step and will display the sampled signal and the magnitude of its Fourier transform. sampling.m
function sampling(x,step) plot(x(1:step:end),'-o') plot(abs(fft(x(1:step:end))))
use x as the input signal
x=(sin([0:pi/8:4*pi]))
Run the function with step=1.Increase the sampling step 2,4,8.... and observe what happens with the spectrum.
What happens with the spectrum as the sampling step increases?
What should be the minimum sampling frequency (maximum sampling step) of a signal?
A 440-V, 60-Hz, six-pole, wye-connected, wound-rotor induction motor with a full-load speed of 1170 r/min has the following per-phase parameters referred to the stator:R 1 = R' 2
Explain in detail the various energy resources and their availability. Explain the following: (a) Types of power plants (b) Selection of power Plants
Starting Methods for Polyphase Induction Motors When high starting torques are required, a wound-rotor induction motor, with external resistances inserted in its rotor circuits
write a short notes of thermal compansation?
How to design an Oscillator Circuit (500 MHz range) with no Op amps?

Determine Total magnetic flux: A ring is composed of three sections. The cross-sectional area is 0.001 m2 for each section. The mean lengths of each section are l a = 0.3 m,
Determine currents in the circuits: Determine currents I 1 and I 2 in the given circuits by applying KVL. Solution We apply KVL for first loop : 10 = 1 I 1 + 1
