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 ...

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 ...

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

“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 ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

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 ...

Today, high-speed digitizer systems operating above 100 MSa/s are being used in a diverse range of applications: operation of single-pulse linear induction accelerators for flash radiographic ...

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 ...

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 ...

A new method for measuring distance based on an optical frequency comb has been unveiled by physicists in the Netherlands. The main benefit of the technique, which involves passing the light from an ...
