This is accomplished by some means of feedback of the output to the input to reduce gain as the input signal becomes larger. The amount of compression is the amount of feedback to reduce gain. One can go to a point to where the stage becomes an attenuator by sufficient feedback. With opamps this can be a very serious problem as they do not work well below unity gain.

A "processor" is a device that does something with the signal. This can any combination of compression, expansion, limiting, distortion, effects, automatic gain control (AGC), etc, etc. The term "compression" is used to describe a type of signal processing where the dynamic range of a signal is reduced without losing it's content. One type of compression is "limiting" which either clips or modifies the dynamic peaks of a signal. Clipping is simply the 'chopping off' of signal peaks. Limiting can also be done by automatic reduction of gain as it peaks (a type of automatic gain control). Limiters are used in radio because dynamic peaks in the audio can cause modulation to exceed 100% resulting in splatter and distortion. If those peaks are limited, the average level of the audio signal, and therefore the "talk-power", can be increased. Another type of compressor is called a "Constant Volume Amplifier" (CVA), which uses AGC to keep the level of the signal at a relatively constant level. (This is different than a limiter because a CVA works by changing the gain throughout the dynamic range, while a limiter only reduces the gain at dynamic peaks.) The CVA is used in sound studios to compensate for changes in the volume of a person's voice into a microphone. (If you watch reruns of Hee-Haw you can see the old-timers will adjust their distance to the mic while they sing; they learned to do this because they often played without the benefit of a CVA in the sound system.) Compared to a limiter, the response of a CVA is slow, and cannot be used to increase the average audio level (talk-power) because it does not reduce or eliminate the peaks that drive modulation over 100%. Brian built a CVA. |

Frank is almost right... the processor that I'm prototyping has an VCA (CVA as Frank puts it) amplifier, amplitude limiting, and a noise gate to cut off unwanted background sound.

Hmmm..... now -that's- useful for a CB radio. I suggest you go here to read for yourself. http://www.analog.com/UploadedFiles/...ts/SSM2166.pdf And I suggested you go get an education, but so far you have just been demonstrating your need to do so. So where's the schematic for your amplifier, Brian? |
