We took a look at op amp integrators in the previous article, Op amps do integration, so it makes sense to round out the picture by covering differentiator circuits. Of course, differentiation is the ...

Square wave voltammetry (SWV) is a sophisticated electroanalytical technique that utilises a superimposed square-wave potential on a staircase waveform to investigate electrode reactions with high ...

There are several ways to evaluate the bandwidth of a signal in the time domain and frequency domain. Previously we looked at the classic relationship of rise time (t r) and bandwidth (f 3db) [Ref 1], ...
