In acoustics, volume refers to amplitude, sound pressure and dynamics. This circuit controls a volume line automatically. It delivers an output voltage of approximately 4Vpp. This voltage remains relatively constant by input voltages ranging from several hundred millivolts to several volts. This electronic circuit is not highly recommended for Hi-Fi applications …

strength, an automatic control of the sensitivity is secured. This will provide an approximately constant signal level at the de- tector, which in turn will result in a more constant audio output, although there is a change of signal voltage in the antenna. This is the general method em- ployed in present avc circuits,
