A compander circuit is used in both the transmitting and receiving portions of the citizen's band radio. Demodulated incoming audio signals are expanded by the compander circuit to increase the dynamic range of the incoming audio signals. Outgoing audio signals from a microphone are compressed by the compander circuit to decrease the dynamic range of the outgoing audio signals before they are amplified and transmitted.

摘要： PURPOSE: A method for coding data by transforming a transition pattern of combined amplitude, phase and frequency, is provided to divide inputted source data into upper bits and lower bits, and to transform the divided data by respectively performing a transition process to a combined pattern of amplitude, phase and frequency. Therefore, compression rates can be raised and error rates in data transceiving can be lowered. CONSTITUTION: Source data inputted in a square wave type are divided into upper bits and lower bits, and are respectively transited to more than one pattern combined with amplitude, phase and frequency in a type converted to a sine wave or binary signals. A data parameter of original source data is pattern-transited to be corresponded to more than one combination pattern by one-to-one, to simplify a parameter of the original source data and reduce/compress data bits and bands. Blocks are connected and compressed with one block sequentially or/and in parallel according to independence in pattern transformation of the compressed data. Data corresponded to an original source input by one-to-one are separately sensed by a pre-described pattern sequence or a programmable pattern parameter generator. The original source data corresponded to more than one combination transition pattern respectively composed of phase, amplitude and frequency by one-to-one are restored based on the compression. The data are restored by the number and type of blocks connected sequentially or/and in parallel with one block according to independence in pattern transformation of the compressed data.
