Notes:
1. The input signal level should be 0 dBm0 for frequencies greater than 100 Hz. For 100 Hz and below, the level should be
–10 dBm0. The output signal magnitude at any other frequency will be smaller than the maximum value specified.
2. Analog signal measured as V

. Assumes ideal line impedance matching.
3. The level of any unwanted tones within the bandwidth of 0 to 8 kHz does not exceed –55 dBm.
4. Assumes normal distribution of betas.
