This course focuses on analyzing signals (sound, voltage, communication transmissions, pressure, images, etc.) and the systems that act on them (circuits, physical echos, mechanical dynamics, ...

Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...

Aliasing is thankfully becoming a less frequent problem due to improved instrument designs. Users should still be aware of it ...

As one of the cutting-edge research areas in modern physics, space-based gravitational wave detection aims at capturing gravitational wave signals in the mHz frequency band. A key technological ...

Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...

Past columns have discussed sampling analog signals and analog-to-digital converter (ADC) technologies. In my experience, though, engineers who simply want to use ADCs rather than design with them, ...

Enabling high-speed swept-source OCT with advanced data acquisition Optical coherence tomography (OCT) has become an ...

In What’s the Difference Between Vibration Sensors, we focused on the advantages and drawbacks of various types of vibration sensors on the market. In signal conditioning and tips, we address the ...
