In audio transformer applications, magnetic saturation causes low-frequency harmonic distortion to increase steadily for low-frequency signals as they increase in level beyond a threshold. In general, materials with a higher permeability tend to saturate at a lower flux density. In general, permeability also varies inversely with frequency.

day audio- frequency amplifiers is the transformer used to couple the plate circuit of one tube to the grid circuit of the next. It is the transformer which determines to a large degree the quality of the sound output and hence the use- fulness of the amplifier. While the aver- age transformer coupled amplifier does

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.

Power Transformers for Audio Equipment. In this article, author Pete Millett explores the different types of power transformers, and why you might choose to use each type in audio equipment. The article addresses issues with low-frequency (50–60Hz) line transformers, but many of the same issues apply to audio-frequency transformers as well. Newcomers to …

Reduce the level from the audio generator to keep the voltage across the transformer below the claimed maximum level, and measure the frequency carefully. Let's assume that you measure a frequency of 399Hz at resonance. Now you can use the formula below to determine the inductance ... L = 1 / ( ( 2π × f )² × C ) L = 1 / ( ( 2π × 399 )² × 100n )
