Reference frequency:
•700 - 1100 Hz
•820 Hz A-Law
•1024 Hz µ-Law

Method 2

With a sine wave in the frequency range of 700-1100 Hz applied to the input
port of any interface, the variation of the gain versus level at the output port
meets the limits given in Table49.
Reference frequency:
•700-1100 Hz
•820 Hz A-Law
•1024 Hz µ-Law
Total distortion includ ing quantization distortion
The quantization distortion is the difference between the original analog
signal and the analog signal (signal plus noise) resulting from the decoding
process. There are two methods of measuring the quantization distortion:
