Signal reception apparatus having automatic level selection function

Abstract

A signal reception apparatus has an automatic level selection function. A comparing circuit compares a level of an input signal with a plurality of sensing levels and outputs a plurality of sensing signals in accordance with the compared result. An auto select level controller receives the plurality of sensing signals from the comparing circuit and selects one of the plurality of sensing levels in response to the plurality of sensing signals. The auto select level controller includes a plurality of flip flop stages. Each of the plurality of flip flop stages has a plurality of flip flops connected in series and is coupled to a corresponding one of the plurality of sensing signals from the comparing circuit. A circuit receives the output signals from the plurality of flip flop stages and selects one of the plurality of sensing levels in response to the inputted sensing signals.
