Requirements for DAB cable-type receiver

After analysis of useful frequencies for DAB (digital audio broadcasting) transmission and the signal levels in CATV (cable television)-networks given, we discuss the theoretical requirements for a cable-type DAB receiver. We show the nature of the digital part and its influence on the characteristics of the receiver's RF-stages. The influence of filters, of nonlinear effects and noise on the receiver's overall performance are discussed. Finally, we present a level diagram for the receiver's stages and discuss data as measured.
