Method for RIAA correction of audio signal with use of transformer and capacitor |
摘要 |
RIAA correction of audio frequency signals is disclosed. A RIAA-correcting pre-amplifier uses a transformer having a primary winding and two or more secondary windings, with two of the secondary windings playing an essential role in RIAA-correction. Frequency correction of a signal coming from one of the secondary windings is carried out on a resistance and capacitance circuit (RC-type of correction), while frequency correction of a signal coming from another of the secondary windings is carried out with the use of an inductance and resistance circuit (RL type of correction).
