Speech Compression Amplifier

Speech Compression Amplifier With Linear Gain = 20V/V

Compression amplifiers are frequently used to prevent overmodulation of AM transmitters. This prevents the creation of spurious modulation products called “splatter”. The “soft knee” of the transfer curve also imparts a “vacuum tube- like” sound to audio signals and musical instruments. The brightness of the LEDs indicate the degree of compression.  Bypass capacitors are not shown. (Circuit is created by Neil P. Albaugh,  TI-Tucson)
