... of two parts; the gain, or magnitude response, and the phase response, which is the phase shift between the output and input sinusoids. Pick several frequencies, and plot the magnitude and the phase of the frequency response as a function of log(). Plot the magnitude in deciBels (dB). Plot the phas ...

LCL Filter Design for Grid-connected NPC Inverters
... This topology (Z1 is finite, Z3 is finite and Z2=0) has Z3 as a result of association of a capacitor and an inductor. With higher values of capacitance, the inductance can be reduced, leading to reduction of losses and cost. Nevertheless, very high capacitance values are not recommended, since probl ...

... impedance to the filter impedance will lead to better filtering of load current harmonics. A single active filter can be used for compensating multiple harmonics as well as for damping resonance in a power distribution system [1]. An active filter can be a VSI or CSI operating on PWM and requires a ...

... The next measurement we took was that of the hold-in (locking) bandwidth. To enable us to measure this we connected a function generator to the circuit input and viewed this input signal on the oscilloscope. The input signal used was that of a sinusoidal wave of at a frequency of 100 kHz and amplitu ...

Ringing artifacts
In signal processing, particularly digital image processing, ringing artifacts are artifacts that appear as spurious signals near sharp transitions in a signal. Visually, they appear as bands or ""ghosts"" near edges; audibly, they appear as ""echos"" near transients, particularly sounds from percussion instruments; most noticeable are the pre-echos. The term ""ringing"" is because the output signal oscillates at a fading rate around a sharp transition in the input, similar to a bell after being struck. As with other artifacts, their minimization is a criterion in filter design.
