gmonopuls

Generate a Gaussian monopulse

Syntax

• y = gmonopuls(t,fc)
  tc = gmonopuls('cutoff',fc)
  

Description

y = gmonopuls(t,fc) returns samples of the unity-amplitude Gaussian monopulse with center frequency fc (in hertz) at the times indicated in array t. By default, fc = 1000 Hz.

tc = gmonopuls('cutoff',fc) returns the time duration between the maximum and minimum amplitudes of the pulse.

Remarks

Default values are substituted for empty or omitted trailing input arguments.

Examples

Example 1

Plot a 2 GHz Gaussian monopulse sampled at a rate of 100 GHz:

• fc = 2E9; fs=100E9;
  tc = gmonopuls('cutoff',fc);
  t  = -2*tc : 1/fs : 2*tc;
  y = gmonopuls(t,fc); plot(t,y)
  
  
  

Example 2

Construct a pulse train from the monopulse of Example 1 using a spacing of 7.5 ns:

• fc = 2E9;  fs=100E9;              % center freq, sample freq
  D = [2.5 10 17.5]' * 1e-9;        % pulse delay times
  tc = gmonopuls('cutoff',fc);      % width of each pulse
  t  = 0 : 1/fs : 150*tc;           % signal evaluation time
  yp = pulstran(t,D,@gmonopuls,fc);
  plot(t,yp)
