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?
theory and general purposes
Q. The response v(t) of a linear system to a unit-step excitation i(t) is given by v(t) = (5 - 3e -t + 2e -2t ) u(t). Determine the transfer function H(s) = V (s)/I (s).
Q. A bandpass filter circuit is shown in Figure. Develop a PSpice program and use PROBE to obtain a Bode magnitude plot for the transfer function ¯H(f) = ¯Vout/ ¯Vin for frequency
pls give me the schematic of it
Q. Write short note on a negative clamper ? A circuit which places the negative peak of a signal at a desired level is known as a negative clamper (1). During the
We can illustrate the direction and strength of a magnetic field by means of drawing 'flux lines'. These have arrows to show the direction of the magnetic field at any point and th
Define Smoothing the Output? The output of a DAC is stepped, such as the analog waveforms which were sampled and held. This stepped, or staircase effect is a distortion, and it
outline what three features you would add (choose the three that you feel would be most advantageous) to the 16 bit version of the processor in order to enhance its power.
Q. A charge q(t) = 50 + 1.0t C flows into an electric component. Find the current flow.
