Notes:
1.
Analog signal measured as VTIP – VRING. Assumes ideal line impedance matching.
2.
The quantization errors inherent in the
µ/A-law
companding process can generate slightly worse gain tracking
performance in the signal range of 3 dB to –37 dB for signal frequencies that are integer divisors of the 8 kHz PCM
sampling rate.
3.
The level of any unwanted tones within the bandwidth of 0 to 4 kHz does not exceed –55 dBm.
4.
Assumes normal distribution of betas.
