MC145554 : A codec–filter is used for digitizing and reconstructing the human voice. These devices were developed primarily for the telephone network to facilitate voice switching and transmission. Once the voice is digitized, it may be switched by digital switching methods or transmitted long distance (T1, microwave, satellites, etc.) without degradation. The name codec is an acronym from “COder” (for the A/D used to digitize voice) and “DECoder” (for the D/A used for reconstructing voice). A codec is a single device that does both the A/D and D/A conversions. To digitize intelligible voice requires a signal–to–distortion ratio of about 30 dB over a dynamic range of about 40 dB. This can be accomplish.

MC14555B : DATA SHEET www.onsemi.com Dual Binary to 1-of-4 Decoder/Demultiplexer MC14555B, MC14556B The MC14555B and MC14556B are constructed with complementary MOS (CMOS) enhancement mode devices. Each Decoder/Demultiplexer has two select inputs (A and B), an active low Enable input (E), and four mutually exclusive outputs (Q0, Q1, Q2, Q3). The MC14555B has the selected output go to the “high” state, and the MC14556B has the selected output go to the “low” state. Expanded decoding such as binary−to−hexadecimal (1−of−16), etc., can be achieved by using other MC14555B or MC14556B devices. Applications include code conversion, address decoding, memory selection control, and demultiplexing (using the En.
