The high pass filter value is a function of the main amplifier gain, the sample frequency, and the feedback attenuation (a). For a gain of 100, a sample rate of 1 ksample/s, and a high pass value ...

High end oscilloscopes with a GHz or better bandwidth generally offer multiple input low pass filters, some analog and some digital. Noise or enhanced resolution (ERES) digital filters are digital low ...

Salisbury, MD. K&L Microwave announced it has developed a family of miniature high-pass filters with cutoff frequencies of 6 to 18 GHz. The filters guarantee rejection of 45 dB at 1/2 the 3-dB ...
