Abstract
Two STC configurations for precision control of RF attenuators, each configuration utilizing a log-scale electronic attenuator, are disclosed. The first configuration includes a D/A converter/linear-to-log module combination to provide a log range ramp; the second configuration utilizes a log table ROM/D-A converter to provide a precision log range ramp, the range so generated controlling the log-scale electronic attenuator utilized in the radio frequency receiver.
