plot sine wave with exponent

Hi there,

I'm trying to synthesise some data for a project I'm doing.

I'm trying to essentially get the datapoints for the f(x) = sin(2x)^3 function with a frequency of 200Hz.

I've looked into other questions here, but so far havent been able to find what I'm looking for.

I'd be really grateful for any tips or solutions. Thanks in advance!

I am not certain what you are asking.

Try this —

L = 30;                                         % Signal Length (s)
Fs = 200;                                       % Sampling Frequency (Hz)
t = linspace(0, Fs*L, Fs*L+1)/Fs;               % Time Vector

f = sin(2*t).^3;

figure
plot(t, f)
grid
xlabel('Time (s)')
ylabel('Amplitude')
title('$f(t) = sin(2\cdot t)^3$', 'Interpreter','latex')

.

This is perfect, thx

I'm working with eeg signals and was trying to synthesise a certain signal complex akin to a sin wave ^3, so this works nicely!

As always, my pleasure!
