Some interesting properties of the first Hall network

The first Hall network is examined in detail to find and optimize the peak magnitude, which occurs in its bandpass response. It is shown that the same network with a reorientation, can act as a bandstop filter. This is also examined in detail and choice of parameters to maximise the peak/minimize the dip is discussed. In both networks, the critical frequency (of peak/dip) can be controlled by a potentiometer, keeping the magnitude of the peak/dip a constant.
