3.00 Credits
This course teaches the fundamental skills of troubleshooting residential and light commercial HVAC electrical system problems. Technicians learn and practice proven diagnostic techniques that they can apply immediately. The goal of the course is to provide technicians with both the skills and confidence necessary to tackle any electrical system malfunction, with emphasis on rapid discovery of the failed component and root cause determination. Prerequisite: Minimum of one year of field experience in servicing and maintaining residential and light commercial HVAC equipment, or Permission of Instructor.
-
4.00 Credits
Designed to introduce students to the basic principles that govern the function and operation of the programmable logic controller (PLC). It focuses on the common input and output devices that are typical in sequential and process control applications. Topics include: PLC applications, logic concepts and ladder diagrams, CPU, memories, input/output devices, safety issues, maintenance techniques, I/O and memory addressing, ladder logic programming language, design of relay operated process, and proper installation methods. Three lectures and three-hour labs. Prerequisite: CMT 171, ELT 141 or Permission of Instructor.
-
4.00 Credits
Students practice the analysis and application of advanced electronic circuits as applied to the telecommunications industry. Topics include frequency response of active filters, oscillators; amplitude modulation, frequency modulation, phase locked loops; pulse modulation concepts; and introduction to television; theoretical and hands-on troubleshooting of test circuits, and analysis by computer simulation. Prerequisite: ELT 153
-
4.00 Credits
Applications of solid state devices in systems, emphasizing power and industrial control circuits. Included are thyristors, operational amplifiers, timers, voltage regulators, opto-electronics, and motor control. This course may be modified in response to rapid technological changes, to ensure that the most important devices are included. Three class hours and a threehour laboratory. Prerequisite: ELT 142 and 261.
-
1.00 Credits
Any project suitable for individual or small group selfstudy, and approved by the department, may be pursued. Students must be highly motivated and selfdirective. The instructor will meet weekly with the students and serve as a resource person. Prerequisite: Variable (Consult department chairperson)
-
4.00 Credits
Linear Electronic Amplifier Circuits. Basic amplifier concepts including gain, attenuation, input and output impedances, frequency response, multistage effects and decibels. Devices studied are Bipolar Junction Transistors (BJT), Field Effect Transistors (FET),and Integrated Operational Amplifier circuits. Three class hours and a three-hour laboratory. Prerequisite: completion of ELT 161 with a grade of C or better.
-
4.00 Credits
This course focuses on radio communications circuits and systems, including tuned amplifiers, mixers, carrier signal modulation, transmission, demodulation, transmission lines and antennas. Emphasis is placed on circuits and concepts common to many types of systems. Circuits of super heterodyne receiver systems are investigated in the laboratory. Three class hours and a three-hour laboratory.
-
3.00 Credits
Deals with basic concepts in Radio Frequency band. Topics included are: transmission media such as coaxial line, and wave guide relationships for impedance, VSWR, gain, and loss in magnetic and electric fields and "s" parameters. Basictheory and operation of the spectrum analyzer and network analyzer will be discussed. Experiments related to the slotted line and measurement techniques for passive RF components such as couplers and dividers will be demonstrated. The basic operations of the pin, attenuator, divider, and coupler are included in the course. Prerequisite: ELT 142 and 161
-
4.00 Credits
Review of AC circuit concepts including Kirchhoff's Laws, Vector Algebra, Phasor diagrams, Magnetism and transformer operation. Polyphase systems including three phase generation, wye and delta connections. Three-phase power. AC and DC rotating machinery. Three class hours and a three-hour laboratory. Prerequisite:Completion of ELT 142 with a grade of C or Better
-
3.00 Credits
Designed to provide work experience directly related to the student's field of study. A learning contract, containing specific educational objectives related to work experience and the student's field of study is developed by the student and the faculty co-op coordinator. Course requirements include a minimum of 180 hours of work in the student's field of study, maintenance of a daily log of hours worked and duties performed, attendance at three two-hour on campus seminars, and a work-related final project. This will allow the student to earn three credit hours. The student can earn a total of six credit hours with additional 180 hours of work experience (without seminars) and an extended final project. The student's performance will be evaluated by the faculty co-op coordinator on the basis of the objectives in the initial learning contract with a grade of Satisfactory or Unsatisfactory. NOTE: The number of credit hours must be determined at the time of registration. Prerequisite: Approval by the ELT Department and the Career and Applied Learning Center (CAL Center).
