PERFORMANCE CHARACTERISTICS

Notes

1.

Figure 7 - to obtain harmonic distortion power

in dBm, add fundamental power in dBm to third

harmonic in dBc e.g. at -10dBm power in line

at

450Hz

third

harmonic

power

is

-10+ (-96) = -106dBm typical.

2.

Third order intermodulation products 2fa-fb

and 2fb-fa are of most importance and are

significantly greater than products 2fa+fb and

2fb+fa. Figure 8 gives the total power of all

distortion products within the voiceband.
