Electrical engineering students rarely leave college with knowledge depth in both digital electronics and RF/microwave theory. The new engineer with digital design skills likely chose that path from a ...

Photonic-based instantaneous frequency measurement (IFM) of unknown microwave signals offers improved flexibility and frequency range as compared with electronic solutions. However, no photonic ...

A revolutionary kind of laser light called an optical frequency comb makes possible a more precise type of atomic clock and many other applications Editor's note: This story was originally posted in ...

Frequency response measurements are a mainstay of RF communications design and generally considered a routine task—unless one of the device ports happens to be at I-Q baseband. Here, the convenience ...

An accurate way to calibrate a frequency source is to use a high-resolution counter/timer to measure the beat frequency, or phase difference, between the source to be calibrated and a reference such ...

Many of today's high-speed serial designs use embedded clocks to avoid routing and timing issues involved with separate data and clock signals and to free up precious real estate on board designs.

Counting frequency is one of those tasks that seems simple on the face of it, but actually has quite a bit of nuance. There are two obvious methods, of which the first is to count zero crossings for ...

What you need to know about understanding frequency response curves of loudspeakers. Note: Paul Dicomo was a great friend to eCoustics and many of us over the past 2 decades. Sadly, Paul lost a ...

Written by Bernard D. Beitman M.D. and Ruslana Remennikova, MS. Since the beginning of human civilization, history has shown a correlation between sound and cognitive, mental, and physical wellness. 1 ...
