这是一个令人叫绝的视频、音频生成器。AVR的运算速度足够处理黑白图像及声音的生成。(但不足以生成彩色图像)。-This is a fantastic video, audio generator. AVR deal with enough computational speed black and white images and sound generation. (But not sufficient to generate color images).

There are many different (and often confusing) terms associated with clock-based devices. This application note attempts to clarify these terms, and hence serves as a comprehensive reference on clock terminology. This application note can be divided into two sections. The first section describes and distinguishes between various clock sources available today. The second section defines and distinguishes between various parameters used to describe clocks. This section also provides methods of measuring some of these parameters.
