Phase Relations in Active Filters
... filter rolloff rate is –6n dB/octave or –20n dB/decade, where n is the number of poles. An octave is a doubling or halving of the frequency; a decade is a tenfold increase or decrease of frequency. So a first-order (or single-pole) filter has a rolloff rate of –6 dB/octave or –20 dB/ decade. Similar ...

As (J' varies between these limits, the Rayleigh wave-phase velocity increases monotonically from 0.87 V t to 0.96 V t where V t is the velocity for a bulk transverse wave. Of parti ...

optimal design of active shunt filter using particle swarm optimization
... Current based compensation is classified as current harmonics compensation. For the current harmonics compensation, the active shunt filter is an ideal device, and considered most suitable because of its reduced cost caused due to the low rating of power electronics(typically 4%-5% of load). In this ...
