Control Fields for the Signaling Encoder and Decoder

Example 8-6 Example 4:

3 kHz deviation, Twist 2.5 dB, Pre-emphasis on.

If sending a 1 (697 Hz low tone and 1209 Hz high tone), the high tone’s deviation is 1.334 (see “Example 2:” on page 279) ⋅ 1.735 (see “Example 3:” on page 279) approximately 2.314 times the low tone’s deviation.

Since the peak deviation of their sum is 3 kHz, the low tone’s deviation is 905.5 Hz and the high tone’s deviation is 2094.5 Hz.
