## Main Question or Discussion Point

Hi

I just wanted to check my approach. I have spectrum I have peak at 10Hz another at 20Hz and a third at 30Hz. The amplitudes are 1000, 500, 250. I want to recreate the signal by summing sine waves.

I assume that I will therefore take

A1 = 1;

A2 = 0.5;

A3 = 0.25;

I will then let y = A1*Sin(2*pi*1000*t)+A2*Sin(2*pi*2*500)+A3*Sin(2*pi*3*250);

Is this correct because when I look at my end result it is not as I wish it to be.

Sorry for mistake in post due to my english
