This article continues from a previous one, “Bandwidth from Transfer Functions” to consider some aspects of frequency response above bandwidth. These include approximation of the unity-gain frequency ...

Graduate student Hossein Jalili displays the millimeter-wave/terahertz phased array chip that he and Assistant Professor Omeed Momeni prototyped in the UC Davis Millimeter-Wave Research Center in the ...

As an ultra-wideband microwave signal, amplitude shift keying (ASK) can be used in many applications, such as electronic warfare, wireless communications and modern radar systems. Initially, ASK ...

A new method for restoring high frequencies within the seismic bandwidth has been applied to a producing field in southern Alberta. This method is different from the conventional methods practiced in ...

Multi-frequency-region parallel sensing (MFRPS) is poised to enable larger-sized, thinner, and more responsive touchscreens.

Microwave component and module manufacture has been well understood and automated for many years. Myriad applications benefit from the capabilities driven by high volumes of microwave point-to-point ...

Mechanical resonance is a pervasive problem in servosystems. Most resonance problems are caused by compliance of powertransmission components. Standard servocontrol laws are structured for rigidly ...

SK Telecom, KT, and LG Uplus will have their entire mobile communication frequency used for providing 3G and 4G (LTE) services (370 MHz bandwidth) reallocated. The Ministry of Science and ICT noted on ...

So far we've examined offset, gain, and timing mismatch. Now we'll look at what perhaps can be considered the most difficult mismatch to combat, which is the bandwidth mismatch between interleaved ...
