A communication system includes transmit and receive paths, a balancing filter, a noise generator, a detector, and an interface. The transmit path is operable to generate data for communication on a communication network. The receive path is operable to receive data from the communication network. The balancing filter is coupled between the transmit path and the receive path. The noise generator is operable to inject a noise signal on the receive path. The detector is operable to measure reflected power in the transmit path associated with the noise signal. The interface is operable to receive a plurality of sets of coefficients for configuring the balancing filter, wherein the detector is operable to measure the reflected power for each of the sets of coefficients.

Echo cancellation balance using noise generator and average power detection

A method, apparatus, and system are provided for controlling the power-mode of a telephonic device. An off-hook condition is detected. A power level for an operation of an electronic device is determined based upon detecting the off-hook condition. Determining the power level includes determining a frequency parameter and/or a pulse-width parameter of a power signal. The power signal is provided for an operation of the electronic device based upon the determined power level.
