同調および切換可能なバンドパスフィルタおよび変調高周波信号用受信器

Title:

同調および切換可能なバンドパスフィルタおよび変調高周波信号用受信器

Document Type and Number:

Japanese Patent JP4504029

Kind Code:

B2

Abstract:

A second secondary resonant circuit (C3,L5,L6) for a second frequency range is connectable to a first primary resonant circuit (C1,L1,L2,L3) of a band-pass filter device comprising a first secondary resonant circuit (C3,L5,L6), so that a second primary resonant circuit is formed. The resonant circuits comprise inductances and capacitances that are adjustable via control signals. An Independent claim is included for a receiver for modulated high-frequency signals.
