Audio transformers are designed for audio range of frequencies, i.e., for frequencies ranging from 20 Hz to 20 KHz and are used primarily in audio circuits. Fig. 1: Representational Image Showing Insides of a Typical Audio Transformer. The important functions of an audio transformer are: 1. Impedance Matching.

In this example, a transformer with a 1:2 turns ratio exhibited an impedance ratio of 1:4. Transformers always reflect impedances from one winding to another by the square of the their turns ratio or, expressed as a formula: Zp/Zs = (Np/Ns)2 where Zp …
