The recent Design Idea “Getting an audio signal with a THD < 0.0002% made easy,” discloses a low THD sine generator which led me to dust off a design that I had published in AudioXpress magazine [1] ...

[Scullcom] has posted the second part of his function generator build ... The design covers audio frequencies (~40Hz to 30KHz) with square, sine and triangle wave outputs. While the XR2206 can ...

the sine wave remained smooth. Running under these heavier loads, we measured the highest sound levels for the EU2200i at 81.2 decibels at the generator. Aside from the clean enclosure ...

From its 1 Hz lower end to its 65.5 kHz upper end, the sine wave shape remains the same ... and should you need an audio function generator and don’t mind a few shortcomings then you should ...
