Digital Waveform Generation

چکیده
This concise overview of digital signal generation will introduce you to powerful, flexible and practical digital waveform generation techniques. These techniques, based largely on phase accumulation and phase–amplitude mapping, will enable you to generate sinusoidal and arbitrary waveforms in real-time with independently controlled waveshape, frequency, phase offset and amplitude, and to design and optimise bespoke digital waveform generation systems from scratch. The book includes a review of key definitions, a brief explanatory introduction to classical analogue waveform generation and its basic conceptual and mathematical foundations, coverage of recursion, DDS, IDFT and dynamic waveshape and spectrum control, and a chapter dedicated to detailed examples of hardware design, accompanied by downloadable Mathcad models created to help you explore ‘what if?’ design scenarios. It is essential reading for practitioners in the digital signal processing community, and for students who want to understand and apply digital waveform synthesis techniques.

This application note describes how to enable a Digital to Analog Converter (DAC) to generate a quick and controlled waveform (rise time and wave shapes) from a predefined set of digital data. The rise time of a waveform generated using Automatic mode can be much quicker, but generation of all waveform shapes is not possible through Automatic mode. Automatic mode can generate square, triangle, ...

Systematic generation of periodic signals with electronically controlled frequency, phase, amplitude and waveform shape (or waveshape) is ubiquitous in nearly every electronic system. The sinusoidal local oscillator in a super-heterodyne radio receiver is a simple example of a signal source whose controllable frequency tunes the receiver. Another example is a step input waveform (e.g. a square ...
