Speech Detection. If the Voice Activity Detector (VAD) option is active, a speech detector is used to identify periods of silence or idle VF channels to provide further compression in addition to ADPCM. This function is performed by the CDP card. The PCM signal is first passed through a high-pass filter to remove DC bias and 50/60 Hz. components that might disturb the speech or modem detectors. The energy of each sample is measured, and the average speech power is calculated. If the power is greater than -31 dBmO (dBmO equals a digital milliwatt), the signal is recognized as speech.

In all MFB Speaker/Amps, we [Philips] mount a tiny sensing device (called a piezoelectric transducer) at the apex of the woofer unit. The transducer converts the sound output into an electrical signal and feeds it back to a comparator in the amplifier. This checks it against the input signal and compensates for any differences. 2, record 29, English, - MFB%20speaker
