Communications Laboratory

Where am I?

This webpage contains documents used in a communications laboratory course (ECE 134L) offered by the Electrical and Computer Engineering Department of the Lyles College of Engineering at the California State University, Fresno.

This communications laboratory uses the TIMS-301C instrument of Emona Instruments (Camperdown, NSW, Australia). The TIMS-301C incorporates a PicoScope, made by Pico Technology (St. Neots, Cambridgeshire, UK).
