Attenuators in Network Analysis

Attenuators in Network Analysis: In various transmission equipments, it is many times required to supress or reduce the levels of the currents and voltages at certain points. To fulfill the need of attenuation, a four terminal resistive network called attenuator is used. Attenuators in Network Analysis are designed to provide a known amount of attenuation …

Chebyshev Approximation

Chebyshev Approximation: Chebyshev Approximation – In the earlier section, we have studied that the Butterworth approximation is the best at ω = 0. But as we move towards cut-off frequency, ωc = 1, approximation becomes poorer. It departs from ideal characteristics. Let us consider an approximation which “ripples” about the normalized magnitude, unity, in the pass …

Normalized Low Pass Filter Characteristics

Normalized Low Pass Filter Characteristics: Normalized Low Pass Filter Characteristics – The passive filters are the filters consisting only passive components such as resistors, inductors, capacitors. These classical filters are designed starting with filter networks such as T type, Π type etc. Low Pass Filter Characteristics is obtained by connecting inductor in the series arm …

Composite Filters in Network Analysis

Composite Filters in Network Analysis: Composite Filters in Network Analysis – In prototype filter sections, the attenuation characteristic is not very sharp in the attenuation band as it is expected. This drawback can be overcome by using m-derived filter sections which are derived from respective prototype filter sections. But it is observed that in the …
