ABSTRACT:
A pilot receiver memory unit is described which is included in a carrier frequency system for storing the control value to the regulating amplifier of each group demodulator in the receiver. The memory unit utilizes a circulating digital shift register having a number of sections equal to the number of space-divided groups. The digital contents of each section which determines the control value can be changed in dependence on determination signals which are supplied through logic means to the register. The control value is converted to analog form before being supplied to the group amplifiers.
