Title: D/a converter
Inventor: TAKAHASHI KOICHI
IPC: H03M1/66
Filed: 1987-04-30
Abstract: PURPOSE:To obtain an analog voice signal with excellent S/N even with the level of an input digital voice signal at a low level by providing an expanding control section controlling the degree of expansion of an expanding section expanding the digital voice signal. CONSTITUTION:A compressed digital signal 10 is inputted from a digital signal input terminal 1 and expanded into a digital signal 12 by an expanding section 2. An expanding control section 3 controls the degree of expansion expanding the level of the digital signal 10 by the expanding section 2. A D/A conversion section 4 converts the digital signal 11 into an analog signal 12. An analog output level adjusting amplifier 5 amplifies the analog signal 12 up to a prescribed level and feeds the result as an output. When the voice signal level of the digital signal 10 is low, the operator operates the expanding control section 3 manually to increase the degree of expansion of the expanding section 2, thereby causing the result of almost no amplification by the amplifier 5. Since the amplification of the voice level is applied mainly in the stage of the digital signal in such a way, thermal noise most likely caused at the output stage of the D/A conversion section 4 is not amplified.
