ELT 112 - Linear Circuits
Covers a wide range of introductory skills and techniques required by an electronic technician. Topics include semiconductor physics, general purpose and zener diodes, linear power supplies, transistors, transistor amplifiers, and basic operational amplifiers. Three class hours, four laboratory hours.
Prerequisite(s): ELT 111 with a grade of C- or better (required) and ELT 102 (taken concurrently or previously completed); TEK 101 (recommended).
Course Learning Outcomes
1. Perform a mathematical and graphical circuit analysis, using a direct current source, a silicon PN diode(s)and one or more resistor combinations, to determine diode current, peak inverse voltage and resistor voltages and currents.
2. Perform a mathematical and graphical circuit analysis, using an alternating current source, one or more silicon PN diode(s) as a rectifier, with a capacitor "filter" and zener diode "regulator" to determine surge current, peak inverse voltage of the diodes, and ripple voltage and load voltage.
3. Perform a complete direct current (dc) "bias" and alternating current "ac" analysis of a discrete bipolar transistor in several common configurations, such as common emitter, common collector, with base bias, or voltage divider bias. Theoritical input impedance, output impedance and voltage amplification are typical results.
4. Using typical laboratory test equipment such as a multimeter, oscilloscope, signal generator and power supplies to experimentally measure with acceptable accuracy: ac ripple, diode peak inverse voltage, current of a simple power supply with filter, and input impedance, output impedance, voltage gain of an unknown amplifier.
5. Write several technical reports of experiments performed in the laboratory in the style that includes but not limited to: objectives, equipment, procedure, data, graphs, and a conclusion. The use of typical computer programs such as: word processor, spread sheet, circuit analysis, and drawing are also required for this Outcome.
6. Analyze an operational amplifier in several of the basic configurations such as comparitor, voltage follower, non-inverting amplifier and inverting amplifier to determine the signal output for a given input.
