The circuit in Figure 1 matches an antialiasing filter's cutoff frequency to an ADC's changing conversion rate. Two main design requirements are high efficiency and the ability to convert signals with ...

Analog variable frequency filters require the use of variable passive components. The higher the slope of the filter, the greater the number of needed variable passive components. These elements are ...

The first part of this series described how data flows through processing steps that create a moving average of stock prices over 65 days. Finite-impulse-response (FIR) filters use the same data-flow ...

This amplifier-based IC implements dual low-pass filters with matched response at cutoff frequencies up to 10 MHz. To build active filters for high-frequency RF applications, designers may construct ...

Noise is a common and pervasive problem in electronics design and debug. At one time or another, almost every designer and debugger of electrical circuits will spend some time dealing with ...
