I've got this code that is supposed to concatenate 2 singals, the problem is that i dont know what time i should put for the program to look how it is supposed to look.
It is supposed to look like this
But instead it looks like this, how should i swap the code.
The exercise sounds like: Generate a useful modulated signal corresponding to a bit string 01001101 in this way following: - for bit 0: a sinusoidal component of amplitude of 0.4V, frequency of 100Hz - for bit 1: a sinusoidal component of amplitude of 0.3V, frequency of 330Hz Each bit has a duration of 20ms without pause between bits (total signal duration is 160 ms). A sampling frequency of 12kHz is used.

@Peter Cristian - why are you using
? Wouldn't that correspond to
159/12000 = 0.1325 seconds
when you should have 0.02 seconds instead which corresponds to the 20 ms duration for each bit. I think you might have been confusing the 160 ms duration for the total signal with the 20 ms required for each bit (though I think using 159 in this manner is still incorrect).
