| A transconductance amplifier like this can be used as a versatile amplifier stage for a wide range of measurement functions, as you’ll see i...
| The TDA7052 IC from Phlips (NXP) requires just two decoupling capacitors to act as a miniature 1-watt audio amplifier.
| The principle of a (preferably) linear amplifier is straightforward: an audio signal modulates (varies in volume and frequency) the small ba...
| A computer is suitable for making (audio) measurements thanks to the sound card that is usually built in. Unfortunately, the audio input on...
