Описание
The modulator receives the bits from the encryption unit, see GSM 05.01 [1], and produces an RF signal. The filtering
of the Radio Frequency (RF) signal necessary to obtain the spectral purity is not defined, neither are the tolerances
associated with the theoretical filter requirements specified. These are contained in GSM 05.05 [4].
