![]() For instance, by providing a square wave for linearity measurements in an audio-system, a simultaneous sawtooth output may be used to drive the horizontal deflection amplifier of an oscilloscope, providing a visual display of the measurement result. ![]() This can be a useful feature when two generated signals are required for a particular application. Many function generators are also capable of generating two different waveforms simultaneously (from different output terminals, of course). They are also used in driving sweep oscillators in oscilloscopes and the X-axis of X-Y recorders. The triangular-wave and sawtooth wave outputs of function generators are commonly used for those applications which need a signal that increases (or reduces) at a specific linear rate. The uses of sinusoidal outputs and square-wave outputs have already been described in the earlier Arts. In fact, each of the waveforms they generate is particularly suitable for a different group of applications. The frequencies of such waveforms may be adjusted from a fraction of a hertz to several hundred kHz.Īctually, the function generators are very versatile instruments as they are capable of producing a wide variety of waveforms and frequencies. The most common output waveforms are sine-waves, triangular waves, square waves, and sawtooth waves. ![]() ![]() A function generator is a signal source that has the capability of producing different types of waveforms as its output signal. ![]()
