CS44600

Signal to Noise Ratio (SNR)

SNR, similar to DR, is the ratio of an arbitrary sinusoidal input signal to the RMS sum of the noise floor, in

the presence of a signal. It is measured over a 20 Hz to 20 kHz bandwidth with units in dB.

SRC

Sample Rate Converter. Converts data derived at one sample rate to a differing sample rate. The CS44600

operates at a fixed sample frequency. The internal sample rate converter is used to convert digital audio

streams playing back at other frequencies to the PWM output rate.

Total Harmonic Distortion + Noise (THD+N)

The ratio of the rms value of the signal to the rms sum of all other spectral components over the specified

band width (typically 10 Hz to 20 kHz), including distortion components. Expressed in decibels. Measured

at -1 and -20 dBFS as suggested in AES17-1991 Annex A.
