In my seminars I often talk about the importance of understanding at least a little electromagnetics theory, even for purely firmware people. But the subject is hard to understand and sometimes harder ...

When it comes to mathematics, the average person can probably get through most of life well enough with just basic algebra. Some simple statistical concepts would be helpful, and a little calculus ...

The Fourier transform underpins so much of our technological lives, in most cases probably without our realising it. The ability to mathematically split a waveform into its frequency components and ...

This idea presents a C++ program that uses the complex class, which enables complex arithmetic. The Discrete Fourier Transform (DFT) is applied to the waveform stored ...

The Fourier transform (FT), a cornerstone of optical processing, enables rapid evaluation of fundamental mathematical operations, such as derivatives and integrals. Conventionally, a converging lens ...

Recently, I wrote automated test software for a multichannel data-acquisition system that I had designed, where sampled waveform accuracy and repeatability were very important. The input waveforms ...

ADC and DAC are the most typical mixed signal devices. In mixed signal testing, analog stimulus signal for an ADC is generated by an arbitrary waveform generator (AWG) which employs a D/A converter ...
