- Find a signal's bandwidth from its harmonicsThere are several ways to evaluate the bandwidth of a signal in the time domain and frequency domain. Previously we looked at the classic relationship of rise time (tR) and bandwidth (f3dB) [Ref 1], captured by this equation: Eric Bogatin also provided Rule of...Apr 23, 2026
- What's that signal's bandwidth?The term bandwidth is used and abused in many situations. I recall one meeting where the word was used to refer to: the frequency content of a particular signal, the frequency response of a specific circuit, the speed of our local area network and the human capacity of the...Apr 23, 2026
- Decibels: Use with cautionDecibels are commonly used in electronic systems that include RF, audio, and more recently, signal integrity. While many engineers already think in decibels, if you mostly work in the time domain, you may not think the same way. Because much of my background is in RF, I tend to...Dec 14, 2020
