Frequency response is defined as: A measure of the effectiveness with which a circuit, device, or system transmits the different frequencies applied to it. It is a phasor whose magnitude is the ratio ...

“Millimeter-wave (mmWave) communications promise Gigabit/s data rates thanks to the availability of large swaths of bandwidth between 10–100 GHz. Although cellular operators prefer the lower portions ...

Measuring RF power at high frequencies is tricky. What if one sensor could cover it all, cut test time, and simplify complex ...

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 ...

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 ...

Today, a vast number of micro-manufactured sensors, actuators and components vibrate at frequencies in the high MHz range. Some examples of these high-frequency vibrating systems include surface ...

[Hans] wanted to see the frequency response of a bandpass filter but didn’t have a lot of test equipment. Using an RTL-SDR dongle, some software and a quickly made noise generator, he still managed to ...

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 ...

A research team has created a quantum antenna capable of precisely measuring terahertz frequency combs for the first time. A research team from the Faculty of Physics and the Centre for Quantum ...
