Abstract:

A digital audio broadcasting system that is capable of providing a large number of high quality stereophonic channels to mobile receivers in an environment with severe multipath delay and fading. Optimum combination of frequency and time diversity to guarantee robust performance in the mobile channel, with its multipath delay and frequency-selective fading effects. The system is based upon a dynamic single channel per carrier assignment of each stereo channel to many carriers. Inter symbol interference degradations caused by multipat ....etc

SUMMARY

A commercial digital IC tester is out of reach of hobbyist.Though it may not have all the facilities of a commercial Ic tester, one can test all type of gates.NOT,AND,NAND,OR,NOR,XOR,XNOR and also 555,741,358 Ics.It has been designed for testing 14 pin Ics with quad to input gates as they are commonly used Ics.However,multiple input gates can also by connecting the remaining inputs to positive or ground.
Computing systems are everywhere.Its probably no surprise that millions of computing systems are built every year des ....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
