The disclosure relates to technology for generating multi-phase signals. An apparatus includes 2{circumflex over ( )}n phase signal generation stages. The apparatus also includes a controller configured to provide a mode input of each of the 2{circumflex over ( )}n stages with an active periodic binary signal with remaining inputs of each of the 2{circumflex over ( )}n stages provided with another periodic binary signal to collectively generate a 2{circumflex over ( )}n phase signal in a first mode. The controller is further configured to provide the mode input of each of 2{circumflex over ( )}(n−1) odd stages with a first steady state signal and the mode input of each of 2{circumflex over ( )}(n−1) even stages with a second steady state signal with remaining inputs of each of the 2{circumflex over ( )}n stages provided with the same periodic binary signal as in the first mode to cause either the 2{circumflex over ( )}(n−1) odd stages or the 2{circumflex over ( )}(n−1) even stages to collectively generate a 2{circumflex over ( )}(n−1) phase signal in a second mode.

In a channelized system having a plurality of channels, an input spectrum having a plurality of signals is received by a receiver ( ). A first attenuation value (V ) is applied to a first variable gain device ( ) and a second attenuation value (V ) is applied to a second variable gain device ( ), wherein the first variable gain device ( ) and the second variable gain device ( ) are within a common signal path. The receiver ( ) is tuned to a desired channel and a first power level is measured within the desired channel. The receiver ( ) is selectively tuned to at least one additional channel and a second power level within the at least one additional channel is measured, independent of the first power level. Based on measuring the power levels, a first modified attenuation value is applied to the first variable gain device ( ) and a second modified attenuation value is applied to the second variable gain device ( ).
