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 ...

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, ...

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 ...

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, ...

Swept-source OCT offers performance benefits in a wide variety of applications. A critical component at the core of the ...

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 ...

The TDS8200 modular sampling oscilloscope and 82A04 phase-reference module from Tektronix enable system jitter measurements of 200 fs rms. According to the company, these devices represent performance ...
