Estimating the term…
A method and apparatus for signal amplification and decision device operation on a signal which has a magnitude, peak value, or other average power that varies over time. In general, a peak detector detects the peak value of a received signal and responsive to the peak value, selectively enables a decision device when the signal is amplified to increase decision device accuracy. The decision may occur before the amplification forces the signal into saturation. Multi-stage amplification in combination with controlled switching or multiplexing may be utilized to selectively IO amplify the signal and selectively initiate decision device operation. The peak detector value may also control signal amplification levels in a multi-stage amplifier. Responsive to the peak value, a switch, which receives as its input the output from one or more amplifier stages, may be controlled to output the signal after a desired amount of amplification.
A method for performing a decision operation on a received signal comprising:
A method for amplifying a signal comprising:
A system for determining at which stage in a multi-stage amplifier system to perform a decision operation on a received signal that varies in peak value over time, the system comprising:
A system for amplifying a received signal based on power level information of the received signal to adapt to changes in power level of the received signals, the system comprising:
The system of claim 20, wherein the control signal is configured to select as an output a signal that has been amplified but which has not undergone non-linear amplification.
