a) Show that the RLC circuit in the figure above is also a bandpass filter by deriving an expression for the transfer function H(s). b) Compute the center frequency, ω o. d) Compute values for R and L ...
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 ...
