ABSTRACT:
An error detector circuit (300) for a discrete receiver indicates bad frames of binary information signals which contain distorted bits of data in numbers so great as to prevent a convolutional decoder (738) from generating, accurately, a decoded signal. A variable threshold generator (440) generates a variable threshold level according to the signal quality estimate for the received signal. When bit errors are detected in numbers beyond the variable threshold or when a first preselected value of the signal quality of a received signal combined with the detected number of bit errors forms a signal beyond a second preselected value, a bad frame is indicated.
