A COST-EFFECTIVE AND USER-FRIENDLY SPECTRUM ANALYZER FOR EDUCATIONAL ENVIRONMENT
- View All
This paper presents the design of an inexpensive and user friendly spectrum analyzer. This is accomplished by utilizing a variable switched capacitive filtering system in conjunction with some commonly used integrated circuits. The resulting system exhibits twelve spectral bands with constant gain and constant quality factor through the entire spectrum. Although the design considers only twelve spectral bands, with simple modifications the proposed technique can be expanded to any desired bands. The primary intention of this paper is to provide a simple method to build and utilize such an instrument in educational laboratories. Commercially available spectrum analyzers are very expensive and not feasible for underdeveloped courtiers with limited resources to obtain such expensive instruments. 2012 American Society for Engineering Education.
