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. Speech processing is a broad term that includes compression, clipping and even DSP. james Thanks ! Vinnie S. |
