The author is a broadcast contract engineer who has a unique way of measuring the carrier frequency of the AM stations in his care. Making off-air frequency measurements of AM broadcast stations can ...

A general-purpose vector signal analyzer offers a low-cost, flexible option for measuring the frequency settling time of PLLs. By Douglas Olney, Keithley Instruments Inc. The frequency-settling time ...

Let’s start our expla nations of loudspeaker measurement graphs with the most basic graph of a speaker’s behavior: the frequency response. Sometimes this is referred to as the amplitude response as ...

The challenges of terahertz-band components and frequency measurement. How a sophisticated combination of optical and electronic components representing advanced principles are being used to measure ...

Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for ...

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 ...

New spacecraft techniques propose using CubeSats, laser rangefinding, and precise Doppler measurements to determine the mass ...
