How do you create a rectangular pulse train in Matlab?
y = pulstran( t , d , func ) generates a pulse train based on samples of a continuous function, func . y = pulstran( t , d , func , fs ) uses a sample rate of fs . y = pulstran( t , d , p ) generates a pulse train that is the sum of multiple delayed interpolations of the prototype pulse in vector p .
What is rectangular pulse shaping?
Rectangular pulse shaping means that each symbol from x is repeated nsamp times to form the output y . If x is a matrix with multiple rows, the function treats each column as a channel and processes the columns independently.
How do you plot a rectangular waveform in Matlab?
Plot Rectangular Waveform and Spectrum
- sWF = phased.
- rectwav = step(sWF); nsamp = size(rectwav,1); t = [0:(nsamp-1)]/fs; plot(t*1000,real(rectwav)) xlabel(‘Time (millisec)’) ylabel(‘Amplitude’) grid.
Which command can be used to generate a rectangular pulse of width 20ms?
Generate 200 ms of a rectangular pulse with a sample rate of 10 kHz and a width of 20 ms. fs = 10e3; t = -0.1:1/fs:0.1; w = 20e-3; x = rectpuls(t,w);
Why is pulse shaping needed?
Its purpose is to make the transmitted signal better suited to its purpose or the communication channel, typically by limiting the effective bandwidth of the transmission. In RF communication, pulse shaping is essential for making the signal fit in its frequency band.
What is autocorrelation of rectangular pulse?
Explanation: The auto-correlation function is the method of correlating the various instants of the signal with itself and that of a rectangular pulse of duration T is a triangular pulse of duration 2T.
What is bandwidth of rectangular pulse?
BW = bandwidth( H ) returns the bandwidth (in hertz) of the pulses for the rectangular pulse waveform, H . The bandwidth equals the reciprocal of the pulse width.
How do you use a rectangular pulse in Matlab?
The rectangular pulse function is also called the rectangle function, boxcar function, Pi function, or gate function….Rectangular Pulse Function
- If a < x < b , then the rectangular pulse function equals 1.
- If x = a or x = b and a <> b , then the rectangular pulse function equals 1/2.
- Otherwise, it equals 0.
What is the Fourier transform of a rectangular pulse?
The Fourier transform of the rectangular pulse is real and its spectrum, a sinc function, is unbounded. This is equivalent to an upsampled pulse-train of upsampling factor L.
