You can do it by adding to waves triangular and sinusoidal.

You should take the absolute values of the sinusoidal wave , using abs().

The frequency of the triangular wave should be 20 times of the sinusoidal wave.

Good Luck

You can generate 2 waves (triangular and sinusoidal) and  add them.

You should take the absolute values of the sinusoidal signal before addition.

The frequency of the triangular wave should be around 20 times of the sinusoidal frequency.

Thank you.

But,Here i have to not only generate the sine wave but also the wave consists of low,medium & high frequencies without use of concatenating.Here,we can use only addition operation such as sin(pi*t)+sin(2*pi*t)+sin(6*pi*t) .But this again give only stationary frequency component.

So your question is as I can understand, do not use the triangular waveform, but to obtain your signal just using the there sinusoidal harmonics?

The answer is no. Just 3 components will be oscillatory around the axis and will not have the triangular shape.

I could try to answer again, if you rephrase your question.

Best.

Hi, Dr. Tanyer

    I want to generate the signal as shown in above figure which consists of one low frequency triangular wave, one medium frequency sinusoidal signal & third componenet should be highest frequecy triangular signal.
