A new instrument has been developed to implement highpass, lowpass and bandpass filters. The Model 601 tunable highpass/lowpass filter contains a tunable 8-pole Butterworth highpass filter followed by ...

Sutter Instrument has developed several filter changers specially designed for wavelength selection over a wide spectral range to any given nanometer value. The Lambda VF-5™, Lambda VF-10, Lambda ...

Columbia, Md.—Paratek Microwave Inc. is now shipping low loss, high performance tunable band pass filter evaluation kits based on Paratek's tunable RF technology. The 0.3 sq. in. filter core features ...

Analog filters implemented in CMOS technology continue to be a cornerstone in the development of modern electronic systems. By integrating active components such as operational transconductance ...

Microcontrollers are digital devices at heart. They can do fancy things like convert analog signals into a digital value but going the other direction is a bit tougher. Pulse-Width Modulation is used ...

Vying for assignments in cable modems, the C5001 and C5003 surface-mount, low-pass filters in IC-grade packages boast of low insertion loss and high stop-band attenuation. The C5001 is earmarked for ...

My previous column described the Sallen-Key circuit for a low-pass filter. At times, you will not find a low-pass filter with the specifications you need in an anti-alias circuit, so you might decide ...

Set up, test and tweak this filter in PartSim to see it’s behavior before building it. The state-variable realization offers the most precise implementation at the expense of many more circuit ...
