In Part 1 ( Ref. 1 ) of this article, we briefly looked at the Wien bridge oscillator before homing in on the bi-quad filter as our best candidate for an oscillator capable of giving 0.0001%/ 120 dB distortion, and showed its full circuit. Treating ...

Over the years, the Design Ideas (DI) column has featured many interesting oscillators, but none that I can recall was specifically designed to produce a really clean sine wave. Putting that omission together with the need to rebuild my old ...

I recently purchased a new oscilloscope for home use. It’s a 250 MHz scope, but I was curious what the actual 3 dB frequency was as most scopes have a bit more upper end margin than their published rating. The signal generators I have either ...

In the classic configuration and most variants of the astable 555 multivibrator circuit, the timing characteristics are based on the charging and discharging of a capacitor. However, it can be argued that since the exponential voltage of a ...
