An encoder is described which features nonuniform qnantizing by combining the processes of encoding and compression. The encoder utilizes the feedback weighing principle and achieves compression in accordance with a 13-segment characteristic. A distinguishing feature of the encoder is that it uses a certain redundancy in circuit elements instead of employing elements with close tolerances.
