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 ...
A digital oscilloscope is one of the most essential pieces of equipment for high school electrical and electronic labs. As useful and popular as it is for high schoolers, the cost of an oscilloscope ...
