Currently, a true random signal generator is a device that can provide electrical signals of various frequencies, waveforms, and output levels. The device is used as a signal source or an excitation source for testing when measuring amplitude characteristics, frequency characteristics, transmission characteristics and other electrical parameters of various telecommunication systems or telecommunication equipment and when measuring characteristics and parameters of components. Signal generators, also known as signal sources or oscillators, are widely used in production practice and in the field of science and technology. The various wave curves are expressed by trigonometric functions. A circuit capable of generating various waveforms such as a triangular wave, a sawtooth wave, a rectangular wave (including a square wave), and a sine wave is called a function signal generator. When testing, researching or adjusting electronic circuits and equipment, it is required to provide electric signals meeting the determined technical conditions for measuring some electric parameters of the circuits, such as measuring frequency response, noise coefficient, and defining degree for a voltmeter, so as to simulate the excitation signals of the equipment to be tested used in actual work. When the steady-state characteristic measurement of the system is required, a sinusoidal signal source with known amplitude and frequency is used. When testing the transient characteristics of the system, a rectangular pulse source with known lead time, pulse width and repetition period is used. And the parameters of the signal output by the signal source, such as frequency, waveform, output voltage or power, can be accurately adjusted within a certain range, and the signal source has good stability and output indication. The signal sources can be divided into four categories, namely sine wave signal generators, rectangular pulse signal generators, function signal generators, random signal generators and the like according to different output waveforms.
