Abstract
A quantizer network is disclosed for decoding an analog signal and providing a four-bit digital output. The analog input signal is divided or quantized into sixteen discrete voltage ranges and applied to sixteen differential amplifiers. Each amplifier has a different reference which must be exceeded before it provides an output signal. The sixteen differential amplifiers are connected to nine latch networks which respond to the signals from the amplifiers and provide a cyclic code in response thereto. The latch networks are connected to a network of logic gates which decode the cycle code into a four-bit digital output signal. The output signals from the logic gate network are applied to output stages which extend the valid time of the output signal from the logic gates.
