Biasing in electronics is the method of establishing predetermined voltages or currents at various points of an electronic circuit for the purpose of establishing proper operating conditions in electronic components. Many electronic devices such as transistors and vacuum tubes, whose function is signal processing time-varying (AC) signals also req...
• (p. pr. & vb. n.) of Bias
conditioning of the magnetic medium during recording by superimposition of a high-frequency or direct magnetic field upon that produced by the wanted signal
This is caused when spill from audio or control circuitry, or an external source, spills onto the audio signal. The additional signal may be at a high frequency (HF Bias), or a DC offset (DC Bias).
