Low-pass filters in microwave engineering serve to transmit signals below a defined cutoff frequency while suppressing higher-frequency components. Design approaches span from classical lumped-element ...

Editor’s Note: This is a four-part series of DIs proposing improvements in the performance of a “traditional” PWM—one whose output is a duty cycle-variable rectangular pulse which requires filtering ...

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 ...

Most digital cameras from the 2000s and 2010s are equipped with an optical element called an optical low-pass filter (OLPF), also known as an anti-aliasing (AA) or blur filter. As the name “filter” ...

In my May blog post, I described the construction of a low-pass filter that used op-amps, capacitors, and resistors. I ignored thermal drift, long-term accuracy, and other characteristics and tested ...
