Active Filters - (43 companies)Active filters are electronic filers that use active components such as voltage amplifiers or operational amplifiers. The amplifier shapes and stabilizes the behavior of the filter, and serves as a buffer interface to the driven component... Search by Specification | Learn More -
Active Band Pass Filters - (17 companies)Active band pass filters are used to attenuate frequencies below and above a range of frequencies (i.e., the bandwidth or passband of the filter). Any signal with a frequency within that band pass range passes easily through the filter. Any... Search by Specification | Learn More -
Active Band Reject Filters - (8 companies)Filter characteristic is an important specification to consider when selecting active band reject filters. Choices include Bessel, Butterworth, Chebyshev, elliptic, Gaussian, and Legendre. Bessel filters are active band reject filters with a passband... Learn More -
Active Low Pass Filters - (18 companies)Active low pass filters pass signals from low frequencies and reject signals from high frequencies. Like other types of active filters, they use active components to shape and stabilize the behavior of the filter, and to serve as a buffer interface... Search by Specification | Learn More -
Active High Pass Filters - (9 companies)...commercial, communications, computers, data acquisition, general, industrial, medical, or military applications. Some active high pass filters are also used in portable devices such as digital cameras and cell phones. Filter characteristic... Learn More -
IC Phase-locked Loops (PLLs) - (69 companies)IC phase-locked loops (PLL) are closed-loop frequency controls that are based on the phase difference between the input signal and the output signal of a controlled oscillator. IC phase locked loops (PLL) are closed-loop frequency controls... Search by Specification | Learn More

Mesta Electronics, Inc.
Digital Power Manager Active Harmonic Filterand Harmonic Manager. True Active Filter The Mesta DPM is a true active filter, continuously monitoring the load currents and responding to the amount and type of harmonics encoun tered. The systeminjects a corrective current, dramatically reducing the line current harmonics and compensating for any fundamental phase shift. The result is a "harmonicless", in-phase line current with near UNITY power factor. Effectively reduces Harmonics The Mesta DPM reduces harmonic distortion to less than 5%...
