Physicists have built a real-number version of quantum mechanics that makes all the same predictions as the standard theory, ...

In this video series I will show you how to divide complex numbers. We do this by eliminating the imaginary number on the denominator by producing equivalent fractions. We do this by multiplying i if ...

Being behind major reports like The Mother of All Breaches and WhatsApp Data Leak, our in-house cybersecurity experts conduct independent, unbiased testing and thorough analysis of password managers, ...

Abstract: Wireless systems often make use of the quadrature relationship between pairs of signals to effectively cancel out-of-band and interfering in-band signal components. The understanding of ...

Abstract: This paper provides a tutorial overview of recent advances in learning control policy representations for complex systems. We focus on control policies that are determined by solving an ...

We are a research-led school with a reputation for excellent teaching and courses with real-world impact. We are based across four sites, comprising more than 2000 students and 190 specialist staff ...

Quantum computers shine when solving involves number or data crunching with huge amounts of inputs. They are designed to tackle complex problems that would take supercomputers from days to being ...

Software Defined Radio (SDR)–the ability to process radio signals using software instead of electronics–is undeniably fascinating. However, there is a big gap from being able to use off-the-shelf SDR ...

Frequency Modulation (or FM) synthesis is a simple and powerful method for creating and controlling complex spectra, introduced by John Chowning of Stanford University around 1973. In its simplest ...
