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?
With respect to serial communication define the half duplex. Half Duplex Transmission: A channel of half duplex can send and receive, but not at same time. It's like a one-la
Define Sigma-Delta Analog to Digital Converters? Sigma-Delta ADCs have the benefit of being implemented almost totally in the digital domain. They are extremely reliable, high
Q. A 20-kVA, 2200:220-V, 60-Hz, single-phase transformer has these parameters: Resistance of the 2200-V winding R1 = 2.50 Resistance of the 220-V winding R2 = 0.03 Lea
Need for Modulation Recognition There are so many communication signals all available with different types of modulation and different frequencies. It is necessary to identify
