so let us assume that there is no error in the process of de-modulation, de-coding and
audio data processing .
Am i right ?

if so, where is the error
most print and parts u have checked .
now there we need some electronics repairing tools like signal generator , CRO etc
but they are not commonly used in gsm
high investment needed
rate of return !!!!
so what we can do ?
