how to produce 12 sine pulse in matlab in matlab

To generate 12 sine pulses in MATLAB, you can use the pulsetrain function to generate a pulse train of 12 pulses. Then, you can use the sine function to generate a sine wave with the desired properties and multiply it by the pulse train to obtain the final signal. Here is an example code snippet:

main.m
% Define the parameters of the sine wave
freq = 1000; % Frequency in Hz
amp = 1; % Amplitude
dur = 1/freq; % Duration of a single pulse in sec

% Generate a pulse train of 12 pulses
fs = 10000; % Sample rate in Hz
t = linspace(0, (dur*12), fs*dur*12); % Time vector for 12 pulses
pulse_train = pulstran(t, (0:dur:(dur*11)), 'rectpuls', dur);

% Generate the sine wave and multiply it by the pulse train
sine_wave = amp*sin(2*pi*freq*t);
sine_pulse_train = pulse_train.*sine_wave;

% Plot the result
plot(t, sine_pulse_train);
xlabel('Time (sec)');
ylabel('Amplitude');

This will produce a plot of the 12 sine pulse train with a frequency of 1000 Hz and an amplitude of 1. You can adjust the freq, amp, and dur variables to change the properties of the sine wave, and you can adjust the fs variable to change the sample rate of the signal.
