ABSTRACT:
In a trap circuit of the bridged-T type, having a delta RC circuit (RR, C1, C2) and a parallel resonant circuit (L, Cp), the capacitance Cp is constituted by variable capacitance diodes (D1, D2) connected via a resistor (8) to a control voltage (Vtone), and the resistor (RR) of the bridged-T circuit is constituted by a PIN diode whose current is controlled by the same control voltage (Vtone) via a resistor (9).
