Fourier synthesis is a method of electronically constructing a signal with a specific, desired periodic waveform. It works by combining a sine wave signal and sine wave or cosine-wave harmonics (signals at multiples of the lowest, or fundamental, frequency) in certain proportions. The scheme gets its name from a French mathematician and physicist named Jean Baptiste Joseph Baron de Fourier, who lived during the 18th and 19th centuries.
Unique VLSI based Fourier Synthesis trainer used to generate the waveform using harmonics. It is very useful in communication and DSP lab. Generation of standard time domain wave forms like Square, Sawtooth, Triangle, Half sine wave, Absolute value sine wave, Modulated waveform etc are possible with the help of this training system.
