Adjust the frequency, amplitude, phase, DC offset, and time scale to see the waveform change like an oscilloscope. Includes sine, square, triangle, sawtooth, pulse, half-wave rectified, full-wave rectified, and noise waveforms.
Frequency controls how many cycles occur per second. Increasing frequency compresses the wave horizontally. Amplitude controls signal height. DC offset moves the whole signal up or down. Time scale controls how much time is visible across the screen. Square and pulse waves use duty cycle.
