PURPOSE:To make the delay time characteristic and the amplitude characteristic without using an amplitude equalizing circuit by connecting a resistor in series or in parallel with one coil or more and capacitor forming a reactance element additionally. CONSTITUTION:Two capacitors 11, 12 are connected in series, a coil 13 is connected in parallel with the capacitors 11, 12, one terminal of a series circuit comprising a coil 14 and a capacitor 15 whose other terminal is grounded is connected to the midpoint of the capacitors 11, 12. Then a resistor 17 is connected in parallel with the coil 13 and a resistor 18 is connected in parallel with the coil 14. Since a delay time equalizing circuit 1 constituted as above has a maximum passing loss near the frequency maximizing the delay time quantity, a projected amplitude frequency characteristic is provided and the passing loss is adjusted by selecting the resistors 17, 18 properly.
