Broadening the Bandwidth Of an Audio Transformer

This stunned me. From what i know audio transformers don't usually have a wide frequency response, sometimes even less than the audible range, and the 200A Oscillator was designed to produce frequencies from 30Hz to 35Khz. Even the best audio transformers sacrifice either low end frequency response for high end frequency response or vice versa.

This is usually taken to be from 20Hz up to 20kHz, but it's not uncommon to extend this in both directions - say from 10Hz to 40kHz - allowing an extra octave either side of the audio band. They are not used at significant power levels, and the maximum will be a …

Works just like any other conventional transformer; audio transformers are designed to work at audio frequencies, i.e. between 20Hz to 20 KHz. Interestingly, the initial need to design to such transformer was to enhance long distancevoice communication.

An audio transformer helps to maintain optimal bandwidth levels, which are largely affected by the power and frequency of the signal. 3 dB (decibels) is the standard measuring point for sound attenuation, and allows calibration of current flow to …

A single ended transformer cannot have a frequency response from 2 Hz to 80 kHz. A more realistic and practical average bandwidth is -1db 25Hz to 25 kHz. This bandwidth is measured with the tube plate resistance included from the signal source. Measured this way, the transformer will now operate exactly as stated with the tube type indicated.

In some of our designs as many as five wires are wound onto the bobbin at the same time, using these methods a bandwidth of 5Hz to 200kHz is achievable with a transformer for single ended operation of a 300B triode.

This is the most commonly transformer type used in high-speed modems. Best of those are quite wideband devices (far more bandwidth than usual 300-3400 Hz as used in telephone). Using two of those transformers and few RCA connectors made …

The audio bandwidth of the circuit is now increased to cover a useful range from about 400Hz to 18kHz as shown in Fig. 5.3.7; still not hi-fi but quite useful as part of an audio amplifier for many isolation purposes.
