a. dBV= decibels above or below a reference voltage of 1Vrms. Signal level is per tone.
b. dBm = decibels above or below a reference power of 1mW into 600 ohms. 0dBm = 0.7746Vrms. Signal
level is per tone.
c. Twist = 20 log (f

Notes:
1.
Both tones have the same amplitude.
2. Band limited random noise 300-3400Hz. Measurement valid only when tone is present.

4. Range within which tones are accepted.
5. Ranges outside of which tones are rejected.
6. Both mark and space have the same amplitude.
7. Band limited random noise (200-3400Hz). Present when FSK signal is present. Note that the BT band is
300-3400Hz, the Bellcore band is 0-4kHz.
