Hi Sanket Shivaji
You can use the below code to generate Hanning Window for a input wave form. You can go through the comments to understand the code.
f_khz = input('Enter the frequency in kHz: '); % Getting the frequency in kHz
Fs = 10 * f_khz; % Use Sampling frequency as 10 times that of input frequency
duration = 1; % Duration of the waveform in seconds
N = Fs * duration; % Number of samples
t = linspace(0, duration, N); % Generating the time vector
x = sin(2 * pi * f_khz * t); % Generating the waveform
w = hann(N); % Generating the Hanning window
x_w = x .* w'; % Applying Hanning window to waveform
% Ploting the waveform
subplot(2,1,1);
plot(t, x);
title('Original Waveform');
xlabel('Time (s)');
ylabel('Amplitude');
% Plotting the Hanning window
subplot(2,1,2);
plot(t, x_w);
title('Waveform with Hanning Window');
xlabel('Time (s)');
ylabel('Amplitude');
% Save the waveform data to an Excel file
filename = sprintf('waveform_%dkHz.xlsx', f_khz);
xlswrite(filename, x_w', 'Sheet1');
