This article describes how to design and build an adjustable, encoder-controlled, two-range sine / square wave oscillator using the SLG47004 IC. To design a simple analog sine wave oscillator (using ...

This file type includes high resolution graphics and schematics. Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from ...

There are several ways to evaluate the bandwidth of a signal in the time domain and frequency domain. Previously we looked at the classic relationship of rise time (t r) and bandwidth (f 3db) [Ref 1], ...

Time-domain finite-difference (TDFD) method is the most dominant approach for seismic wavefield simulation. Due to the memory and computational cost of the computer, finite-difference (FD) simulations ...
