Moog purists who felt uncomfortable with the release of the Animoog iPad app earlier this week can take solace in the launch of The Ladder, a new rack-mountable hardware processor that's based on Bob ...

Most hobbyists use crystals as an external clock signal for a microcontroller. A less common use would be to make a bandpass filter (BPF) for an RF signal. [Dan Watson] explains his crystal ladder ...

Monosynths lie at the heart of Moog’s heritage. With the Minimoog Model D, Bob Moog not only brought the Moog sound to the masses, but set a template for analogue synth design that still influences ...

Editor’s note: Most modern designs have been using voltage mode elements like op-amps for implementation of various electronic circuits. These elements are used widely due to their small sizes and ...

For many modularists, the filter is the go-to tool for sound-shaping on the fly, which is why so many filters have an oversized knob for the cutoff. In essence a filter is a module that takes incoming ...

In a world of digital electronics, there are still necessary functions for analog circuits, especially filters. When real-world signals are digitized or synthesized, for example, analog filters are ...
