Booster for BS / CS right-handed / left-handed broadcasting and CATV

摘要

PROBLEM TO BE SOLVED: To compensate for a transmission loss not only when the transmission loss monotonically increases as the frequency increases but also when the transmission loss is provided with a frequency dependence such that the transmission loss decreases or increases in a specific frequency band. / Provides a booster for CS-IF level adjustment. An input signal is analog-digitally converted into a digital signal, the digital signal is separated into signals for each broadcast channel, the signal level for each separated broadcast channel is adjusted, and each adjusted broadcast channel is adjusted. The signals are combined into one signal, digitally analog-converted, and output is a signal having the same frequency arrangement as the input signal and each broadcast channel signal adjusted to a predetermined level.
