How do i plot this equation in the time domain
显示 更早的评论

What is the value of K? Why do you write m as a function of t when it actually is a constant? What about the "1" in the argument of the cosine function? We can help if you provide us with all the details surrounding your equation.

I go the function from this, where The equation of the modulated signal is: s(t) = Ac • [1+K • m(t)]cos(2πfc t) = 5 • [1+K • m(t)]cos(2π1 t) , and i need to plot the signal in the time domain which is something i have no idea how to do and im i cant find anywhere how :(

see what this does:
t = 0:0.01:2*pi;
fun = @(t) 5 * (1 + K * m) .* cos(2*pi.*t)
Note that you have to define K also as a numeric value before you can claculate something with this...
