how to add two sinusoid?

[muaythai2006]

I was asked to generate two sinusoids at the right freqnecies and add them samples by samples. The first frequencies of the first sinusoids is 1336 and other is 770.

1336 this is the highest frequency ...so u have to choose 2*1336 as the sampling frequency ...and sample both the sinusoids...then add them sample by sample

 

[echo47]

fs = your unspecified sample rate

for (n=0; n<1000; n++)
  output[n] = sin(2 * pi * 1336 * n / fs) + sin(2 * pi * 770 * n / fs);

Beep! You've just pressed "5".

I hope that wasn't your homework.

u could use signal synthesis

use function generator to generate them and add them using summer of gain 1
