Acronym of COBBA


( Common Base Band Analoque ) COBBA somehow IC. This IC converter analog signals to digital, and also digital-to-analog. The incoming waves antenna, after this, that by the IC RF were lines RX entered the IC COBBA in unit AF. This is your thirty-first, the incoming signal from the RF by communication lines PCM to the block MCU. In this block information via the IC CPU, the memory, the temporary phone will be poured, then the IC COBBA again through the same communication lines, etc. information from the temporary memory ... conversion to analog signal that works through the loud speaker adjustable, will be used. Since the species for which information should be part of the mobile ... the sound by the microphone. for the analog signal. These signals after login to the IC COBBA, etc. convert to digital. then through the lanes of the PCM unit MCU has transferred in the temporary memory to keep them and as soon as a Channel, Mobile is all the information for the part of the microphone unit through RF to the BTS is sent.
