Abstract
A method and circuit for indicating signal faults in wireless transmissions, particularly, a carrier leak, includes an input to receive a wireless signal, a bias detector that detects a bias in a portion of the signal and outputs a bias value indicative of the bias, an evaluator configured to compare the bias value to at least one allowable transmission signal value, and output a signal when the bias value is outside the allowable transmission signal value, and an output, responsive to the evaluator, to indicate a carrier leakage in the wireless signal. A buffer may be provided between the input and the evaluator. The sensitivity of the circuit may be adjusted and a protocol determination may be made.
