reconstructed without error‚ provided the noise picked up in transmission is not enough to prevent identification of the 1s and 0s. An hour of music can be stored on a compact disc using about 6 billion binary digits. In a digital system‚ a more precise representation of a signal can be obtained by using more binary digits to represent it. While this requires more digital circuits to process the signals‚ each digit is handled by the same kind of hardware. In an analog system‚ additional resolution requires

Environment Temperature Control Using Modbus and RS485 Communication Standards Abstract – This paper reports an undergraduate engineering team’s effort to develop a system which emulates a curing process chamber found in many industry settings. Based on industry utilization of bus protocols‚ it has been determined that the de facto standard Modbus protocol under the industry recommended standard interface RS485 is an appropriate communication method for this closed-loop control system.

INTRODUCTION CDMA stands for CODE Division Multiple Access. Code division multiple access ( CDMA ) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access ‚ which is where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this to be achieved without undue interference between theusers CDMA employs spread- spectrum

In the paper we derive minimum non coherent distance(dnc)of block coded TAPSK and compare it with different modulation techniques‚ i.e. 8-PSK and
