BE has put a name on its new 50 kW AM transmitter, first reported here in July. The company will show its 4MX 50 AM transmitter at the NAB Radio Show. The model name refers to a Fourier Modulation (4M ...

This course focuses on analyzing signals (sound, voltage, communication transmissions, pressure, images, etc.) and the systems that act on them (circuits, physical echos, mechanical dynamics, ...

Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform, ...
