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 ...

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 ...

You have surely read about signal bandwidth in various technical literature, but exactly what is it and why does it matter in signal processing projects? All circuits and transmission paths limit the ...

5G is coming, and with it, the promise of faster internet that will support innovations like streaming virtual reality, self-driving cars, and smart home and city infrastructure. But before it rolls ...

Radar waveforms are classified into three categories based on the bandwidth of operation. With multiple waveforms available for use, such as FMCW and pulse-modulated, it’s imperative to decide on 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 ...

Analog measurement resources in today’s mixed-signal ATE use ADCs, and the test methodologies are based on DSP. Two types of measurement resources are distinguished by the relationship of the test ...
