- Figure 1. This simple circuit synthesizes a grounded variable resistance with a hyperbolic-control characteristic
- Figure 2. You can realize a floating variable resistance, with hyperbolic taper, with this circuit. Note that fixed resistors with the same number are matched pairs
- Figure 3. The basic circuits of figures 1 and 2 have been used in the design of a bridged-T notch filter with a variable notch center frequency and a linear frequency scale
- Figure 4. The Spice-simulated notch center frequency for the circuit of Figure 3 versus the normalized wiper position shows that the notch center frequency is a linear function of the control position
