ADC & DAC Converter API
ADC/DAC data-converter maths as an API, computed locally and deterministically. The resolution endpoint turns a bit depth into the number of quantization levels (2^N), the LSB step for a given reference voltage (in V, mV and µV), the full-scale range, the ideal signal-to-noise ratio (6.02·N + 1.76 dB) and dynamic range, and — given an input voltage — the digital output code. The sampling endpoint covers Nyquist: the minimum sample rate for a signal bandwidth (2·f_max), the Nyquist frequency for a sample rate (fs/2), whether a signal is adequately sampled, and the alias frequency a tone folds to, |f_in − round(f_in/fs)·fs|. The quantization endpoint gives the maximum quantization error (LSB/2), the rms quantization noise (LSB/√12), the ideal SNR, and the effective number of bits (ENOB = (SNR − 1.76)/6.02) from a measured SNR. Everything is computed locally and deterministically, so it is instant and private. Ideal for embedded, DSP, audio and instrumentation app developers, data-acquisition and converter-selection tools, and electronics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is data-converter & sampling maths; for media bitrate and file size use a bitrate API and for AC reactance and resonance use a resonance API.
