Notes:
DDA
1. The input signal level should be 0 dBm0 for frequencies greater than 100 Hz. For 100 Hz and below, the level should be
2. Analog signal measured as V
3. The quantization errors inherent in the µ3/A-law companding process can generate slightly worse gain tracking
4. The level of any unwanted tones within the bandwidth of 0 to 4 kHz does not exceed –55 dBm.
5. Assumes normal distribution of betas.
