Abstract
Many application of the RC parallel-T network, only two performance characteristics are considered important the frequency and depth of the attenuation notch. In this paper the design presented, active notch distributed RC network (URC̄) circuit from design values. The proposed circuit configuration consists of URC̄, one external resistor (Rn) or capacitor (Cn) and single gain amplifier. The parameters of the proposed circuit can be adjusted to improve the magnitude response with notch tunable frequency. This structure reduces an amount of circuit complexity and is simple to use for application. The experiments and computer simulation showed good agreement with theoretical values. The active notch URC̄ can application to experiments high frequency active band-pass filter, sinusoidal wave oscillator and frequency discriminator.
