Products/Services for Electronic Band Stop Filter
Active band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies. These devices are also known as bandstop or notch filters. Learn More about Active Band Reject Filters
Optical bandpass filters are designed to transmit a specific waveband. They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference in the transmitted light. Search by Specification | Learn More about Optical Bandpass Filters
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 about Active Filters
IC electronic filters are frequency-selective circuits that consist of devices such resistors, capacitors, inductors, transistors, or operational amplifiers coupled with reactive components. Search by Specification | Learn More about IC Electronic Filters
Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics. Search by Specification | Learn More about Signal Filters
RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters. Search by Specification | Learn More about RF Filters and Microwave Filters
Digital filters use digital signal processing (DSP) to perform numerical calculations on sampled values of a signal. Learn More about Digital Filters
Electronic counters and electronic timers are completely electronic units for performing a variety of counter or timer functions. Search by Specification | Learn More about Electronic Counters and Electronic Timers
RF band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies. These devices are also known as bandstop or notch filters. Search by Specification | Learn More about RF Band Reject Filters
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). Learn More about Active Band Pass Filters
Filter wheels hold and position multiple filters for various imaging applications such as machine vision and spectrophotometry. Search by Specification | Learn More about Filter Wheels
SAW filters are electronic filters that are designed and manufactured using surface acoustic wave (SAW) technology. SAW uses piezoelectric transducers that, when excited, produce waves that are used to filter frequencies. Learn More about SAW Filters
Passive filters are implemented using only passive components such as resistors, capacitors and inductors. These filters do not produce any amplification of the input signal. Learn More about Passive Filters
Long pass filters transmit a wide spectral band of long wavelength radiation while blocking short wavelength radiation. Short pass filters transmit a wide spectral band of short wavelength radiation and block long wave radiation. Search by Specification | Learn More about Long Pass Filters and Short Pass Filters
High-efficiency particulate air (HEPA) filters and ultra-low particulate air (ULPA) filters are designed to screen particles larger than 0.3 µm Search by Specification | Learn More about HEPA Filters and ULPA Filters
