Design and Implementation of Astable Multivibrator for Different Applications in Communication System

This paper aims at presenting the design and implementation of astable multivibrator for various applications of communication system such as is digital data transmission, RFID system, FSK generator and pulse position modulation etc. An astable multivibrator is constructed for given specification one of which is, it must have a duty cycle of 0.75. The workability of the proposed circuits is confirmed through PSpice, SIMetrix and Tina pro simulations tools and finally the experimental work is compared. Through this paper one can get the idea about the use of PSpice, SIMetrix and Tina pro software and found the better results. Because they are low cost, fast simulation techniques for the linearity and accuracy of the circuit performance and reliability is reported by using these tools. The results are explored with browsing output data facility.
