Speech-Pass Filter

A speech-pass filter circuitry is shown in the the schematic diagram below. This speech circuit is useful in an application when the frequency spectrum of the signal should be limited to contain only speech (human voice) information. Voice recording or radio broadcasting is some example of such application. Corner frequencies of 300 and 3000 Hz is provided by high pass […]

Audio Line Driver

The video application uses LT1206 as a main components because it has outputĀ  derive capability and suitable bandwidth. So that the LT1206 can also be used for audio applications. Here is the schematic diagram: In this circuit the LT1206 combined with the LT1115 low distortion, that has a very low noise audio buffer with a gain of 10. The frequency […]
