Driving an analog-to-digital converter (ADC) for optimum mixed-signal performance is a design challenge. Figure 1 shows a standard ADC driver circuit. During ADC acquisition time, the sampling ...

A filter that blocks high frequencies and allows lower frequencies to pass through. Such filters are used in devices such as POTS splitters that direct phone and DSL signals to different lines.

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 ...

The circuit was designed with the combination of high pass filter and low pass filter to create a notch filter circuit. High Pass Filter – an electronic circuit that allows the passage of high ...

180SMIC_LPF_05 is based on 3rd order Butterworth low-pass filter (LPF) with cut-of frequency adjustment in a wide range. There are 2 modes for cut-off ...

Any pointers to good resources on audio filters for WAV files (particularly low-pass filters) implemented in Java? I've found a goodly amount of resources on DSP and filters, but when it gets to ...
