The vibration load subjected to many products is the combination of several random processes corresponding to different application conditions, such as the various field road load inputs for automotive components. Sometimes the input loads are the combination of random and sinusoidal vibration. Due to the convenience of test setup and monitoring, the sinusoidal vibration sweep tests are often used for product durability validation by many automotive and consumer product manufacturers. It is therefore important to correctly correlate the sweep ....etc

Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc

Digital-to-Analog Analog-to-Digital
Data Handling Systems
Both data about the physical world and control signals sent to interact with the physical world are typically analog or continuously varying quantities.
In order to use the power of digital electronics, one must convert from analog to digital form on the experimental measurement end and convert from digital to analog form on the control or output end of a laboratory system.
Digital-to-Analog Conversion
When data is in binary form, the 0's and 1's may be of s ....etc

BUILT IN SELF TEST FOR A CMOS ALU

Abstract:- A technique is proposed for implementing BIST (built-in self-test) in a CMOS arithmetic and logic unit (ALU). The approach covers single stuck-open faults and all functional faults that do not induce memory effects. The specific fault set covered by the test includes: (1) all single stuck-open faults on n and p transistors anywhere in the ALU (F1 faults); and (2) all functional faults that affect any single-bit slice of the (F2 faults), a functional fault being any fault that changes one combinati ....etc
