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

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, ...

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 ...

Signals that carry information play a central role in technology and engineering — signals ranging from sound and images to sensors, radar, communication, MRI, ultrasound, touch-screens, GPS, and ...

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

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, ...

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 ...
