In the present work the design of the notch filter with adjustable center frequency and quality factor is described. The scope of application of the developed low-frequency notch filter includes various radiophysical devices, such as low frequency radio equipment and devices for registration of biomedical information. Structural diagram of the filter and its operational features are shown, also the formulas for calculating the characteristics of the filter are given.
