Determining the State of <i>N</i> Diodes in a Multi-Diode Network

Many circuits appearing in pulse and digital electronics are multi-diode networks. In such networks diodes can typically be modeled as either on or off. Determining the states of all diodes can become quite challenging (and sometimes frustrating) for the undergraduate student who has not yet developed intuitive insight into the subject. In this paper a logical and systematic procedure for determining the state of all the diodes in a multi-diode network is presented to simplify the circuit analysis, ease the frustration, and help the student develop physical insight into the design and analysis of electronic circuits. </jats:p

A Laboratory Experiment on Communication Electronics

In this paper a laboratory experiment illustrating applications of the bipolar junction transistor (BJT) to communication electronics when the BJT is operating in its large signal nonlinear region is described. The analysis of a large signal tuned amplifier, frequency multiplier, mixer, A.M. modulator, limiter, and oscillator are among those circuits studied. </jats:p
