Supports biamping, directcoupled (no blocking capacitors), and adjustable control of and lowfrequency distortion. Frequency and amplitude are adjustable. The signal generator DIY kit is a professional product that can generate sine wave, TripleCornered wave, square wave, and positive and negative sawtooth wave. This is a solderandinstall DIY kit. Uses ICL8038 and a speed operational amplifier to improve accuracy. Capable of outputting sine, TripleCornered, square wave, and forward and reverse sawtooth waveforms. Frequency range: 5 Hz to 400 kHz; duty cycle range: 2% to 95% (adjustable). Practical applications Laboratory testing and calibration of audio amplifiers, filters, and other signal processing circuits. Educational use in electronics labs or DIY projects to learn waveform generation and waveform characteristics. Prototyping and characterizing circuits that require precise timing and waveform control, such as RF, audio, and sensor signal conditioning.
