Recurrent neural networks - predicting periodic signals

Oscillators are circuits that produce specific, periodic waveforms such as square, triangular, sawtooth, and sinusoidal. In order to generate output, oscillators generally use some form of active device-lamp, which is surrounded by resistors, capacitors, and inductors. Two main classes of oscillators are relaxation and sinusoidal. Triangular, sawtooth and other non-sinusoidal waveforms are generated using relaxation oscillators, while sinusoidal oscillators consist of amplifiers with external components to generate oscillation. Normally, no harmonics are present in pure sine waves and they consist of a single frequency.
