This is an economically priced Function Generator, signal source for a wide variety of applications in electronics, communication and control systems laboratories. The IC used is a high frequency function generator that produces low distortion sine, triangular, sawtooth and square waveforms from frequencies less than a Hz to 20MHz. A minimal of external components are needed which make the unit very reliable and robust. The desired output waveform is selected by logic control and may therefore be done electronically as well.
Basic principle of function generation used is relaxation oscillation with periodic charging and discharging of a capacitor through constant current source. The charging/discharging currents are accurately controllable and the associated circuits support high frequencies very well. A sine shaping circuit converts the triangular waveform to sine wave of constant amplitude. The sine wave is useful for frequency response studies of amplifiers, filters and other electrical systems, while the square wave finds applications in transient response studies. Triangular wave is a standard input signal for the study of steady state error in feedback control systems. All power supplies are IC regulated.
