BIDIRECTIONAL ADAPTIVE VOICE FREQUENCY REPEATER
A "high" pass filter (117 or 123) is employed to shape the low frequency input characteristic to a bidirectional repeater including echo cancelers (114 & 115). This frequency shaping eliminates excessive low frequency signal components from being supplied to the echo cancelers. Consequ...

| Zusammenfassung: | A "high" pass filter (117 or 123) is employed to shape the low frequency input characteristic to a bidirectional repeater including echo cancelers (114 & 115). This frequency shaping eliminates excessive low frequency signal components from being supplied to the echo cancelers. Consequently, the number of taps, i.e., (Figure 2. 216-0 -> 216-N) amplitude coefficients, required in the echo cancelers (114, 115) is minimized. |
