al production and electrical and electronic Labs one of the electronic instrument. Signal generator can has multiple achieved method, and frequency more high produced waveform more more of signal generator more good, can from signal generator of produced conditions and the using area aspects consider its achieved method digital system in the needs of special signal, as square wave, and triangle wave, such as in munications, and broadcast, and TV system in the, are needs RF (high frequency) launches, here of RF wave is carrier, to audio (low frequency), and video signal or pulse signal carrying out, on needs can produced high frequency of oscillation Manager. In the field of industry, agriculture, biomedical, such as highfrequency induction heating, melting, quench, ultrasound Diagnostics, such as magic resonance imaging, you need power or large or small, or high or low frequency oscillator. Waveform generator widely used in major universities and research establishments. With the advances in science and technology, social development, a single waveform generator can no longer meet the needs of the people, and we design the multiple waveform generator. Keywords: sine wave。 wave。 triangle waves。 lowfrequency signal source
