  • Receiver with controllable amplifier means
    Patent number: 6163685
    Abstract: In a receiver for digital symbols, an input signal received by a tuner is passed via a SAW filter and a controllable amplifier to an input of a demodulator. The output signals (I,Q) of the demodulator are passed via controllable amplifiers to analog to digital converters. In order to avoid the use of a feedback signal from the digital part of the receiver to the analog part it is proposed to use first control means for controlling the output signal of the demodulator and second control means for controlling the output signal of the analog to digital converters. An additional advantage is that both control means can be optimized for their respective environments.
