Audio Amplitude Compressor

Jan 19th 2001
A True RMS converter (LTC1967) monitors the output signal amplitude and provides a proportional dc feedback voltage. This dc voltage controls an LT1256 fader circuit which linearly selects the amount of signal from two amplifier stages. One amplifier attenuates the input signal by 4 while the other amplifier gains up the signal ...

LVDT Signal Conditioning

Aug 24th 1998
An LVDT transformer is exited with a fixed frequency sine wave. The distance of displacement of the movable core will change the amplitude of the transformer output which is is converted to a dc voltage by the LT1967 True RMS converter. The direction of the core movement is indicated by the phase shift of the sine wave and is ...
