About Signals Generator
This app transforms your phone into a powerful handheld dual-channel signal generator for generating sound signals (and can also be used by professionals to generate audio electrical signals). Signal types include: sine wave, triangular wave, sawtooth wave, rectangular wave, Gaussian noise, Rayleigh noise, gamma noise, salt-and-pepper noise, uniformly distributed noise, pink noise, red (brown) noise, blue noise, purple noise, longest sequence signal, frequency-sweep signal, elementary function waveform, and hand-drawn waveform. It can switch between single-channel and dual-channel operation; the dual channels can independently set waveforms and their parameters. The parameters of the signal, such as amplitude, frequency, and phase, can be adjusted. The waveform can be scaled freely using gestures or buttons, making it simple and easy to use. Support interface color selection. This application is normally used to generate sound signals and poses no risks. Special instructions for circuit measurement: Professionals can utilize this application for circuit measurements, with audio electrical signals being output through the left and right channels of headphones. Please ensure safety: You must possess sufficient professional knowledge, and isolation equipment must be added to high-voltage circuits. Circuit measurement involves risks. The author of this application will not be responsible for any personal or equipment damage caused by the correct or incorrect use of this application.
