  • Publication number: 20250004496
    Abstract: 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.
    Type: Application

  • Patent number: 6735423
    Abstract: In a channelized system having a plurality of channels, an input spectrum having a plurality of signals is received by a receiver (10). A first attenuation value (V1) is applied to a first variable gain device (12) and a second attenuation value (V2) is applied to a second variable gain device (14), wherein the first variable gain device (12) and the second variable gain device (14) are within a common signal path. The receiver (10) is tuned to a desired channel and a first power level is measured within the desired channel. The receiver (10) 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 (12) and a second modified attenuation value is applied to the second variable gain device (14).
