Analog to Digital Conversion
Analog to Digital conversion is 8000 samples per second of 13 bits each. Bit rate of 104 kbits/s.
When it is considered that 8 subscribers use one radio channel, the overall bit rate would be 8*104kbits/s. Recalling the general rule of 1 bit per hertz, this bit rate must be reduced somehow- this is achieved using segmentation and speech coding. But I have A/D converter and i need 12000 samples per second of 16 bits each.
