Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...
Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...
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 cutoff ...
