The changeover switch as a frequency transformer of RC driving-point impedances

The use of a changeover switch (COS) is suggested to enable the transformation of RC low-pass networks to other frequencies to be realized without the change of any element within the network. In addition, since the COS used in this application has multiple positions, it can be operated in different permutations, each modifying the characteristic of the network in the frequency domain. These characteristics show that the COS can be viewed as an additional electrical element to be used in network synthesis.
