Many of today’s DAC require a circuit that has a differential input and will remove common-mode errors, reduce the out-of-band noise produced by the delta-sigma modulator and produce a single-ended ...

Many of today’s Digital-to-analog Converters (DACs) require a circuit that has a differential input and will remove common-mode errors, reduce the out-of-band noise produced by the delta-sigma ...

In the last edition of Don’t Fear the Filter, we built up two examples of the simplest and most-used active filter of all time: the two-pole Sallen-Key lowpass. This time, we’re going to put two of ...

Having pondered RCRC two-pole filters the other day, I thought I ought to work out the transfer function for myself – something the little grey cells had not done for a very long time. It eventually ...

Waldorf has dropped a new member into its ever-growing Eurorack modular range in the form of the vcf1 and it promises to utilise the best bits from the 2-Pole filter and Rocket monosynth. Not content ...
