[0002] Waveform generator is a relatively common analog signal generation circuit, which is widely used in signal conditioning circuits or hardware debugging. For example, in hardware debugging, a single-chip microcomputer edits a complete program, and when debugging a serial port program, a fault occurs. If you don’t know how to eliminate the fault In some cases, it is necessary to use the output port of the virtual single-chip microcomputer of the waveform generator, and debug the serial port to eliminate the fault factors; in addition, various waveforms are often used in the debugging of analog circuits, not just sine waves, which are usually used The signal source is bulky, which is not conducive to handling, complex operation, and cannot quickly and easily generate the required signal. Therefore, a simple, convenient and easy-to-move waveform generator device is needed, with stable output signals and strong anti-interference. Again, it is not a simple The output single sine wave signal, common triangular wave and square wave signals are also required, which requires that the volume of the waveform generator device should not be too large, but it must also ensure stable output performance, strict requirements on the waveform generation circuit, various devices The waveform generation device with high error requirements and high precision requirements. Nowadays, the market lacks a waveform generation device that is easy to operate, convenient to move, complete in function, and can generate a variety of waveforms, and the waveform must be stable in the application of analog circuits. , no glitch, solve the problem that the waveform generator device has three waveforms of sine wave, triangle wave and square wave at the same time to meet the needs of debugging, the conditioning circuit is simple, and the functions are complete.
