COURSE DESCRIPTION:

Enables the student to study, construct, test and evaluate methods of testing and controlling common industrial processes.  Includes sensing systems, transducers, measurement techniques, systems interfacing, process control, and data acquisition.  68 contact hours
5.

COURSE GOAL:

To learn the design and repair of active devices circuits which includes operational amplifiers circuits, operational amplifiers frequency response stability and compensation, operational amplifier applications, oscillators, active filters, voltage regulators, thyristors and unijunction transistors, optoelectronic devices, and three terminal IC regulators.  This course is replete with numerous experiments and quick-labs that strive to provide the student the necessary skills.

6. COURSE OBJECTIVES:
  When students have successfully completed this course, they will understand the following and be able to:
  (A) Describe the operation of a level shifter and differential amplifier.
  (B) Distinguish between the operational amplifiers, inverting and noninverting modes.
  (C) Demonstrate offset compensation for inverting and noninverting OP-AMP  configurations.
  (D) Design and predict the performance of OP-AMP integrator and differentiator circuits, constant current sources, current to voltage, and voltage to current convertors
  (E) Design and predict the performance of OP-AMP circuits to generate sine, co-sine, triangle, square and staircase waves.
  (F) Design and predict the performance of OP-AMP active filter circuits.
  (G) Design and predict the performance of OP-AMP linear amplifier circuits using single supply biasing.
  (H) Design and predict the performance of basic OP-AMP circuits using Norton OP-AMPs.
  (I) Explain the difference in performance between instrumentation amplifiers (Ias) and standard OP-AMPs.
  (J) Understand what an oscillator is and how it works.
  (K) Understand the basic principles of positive feedback.
  (L) Understand the basic operation of various types of sinosoidal oscillators that use RC networks in the feed back loop, including Wien-bridge, phase shift and Twin T Oscillators.
  (M) Understand the basic operation of various oscillators that use LC networks, crystals, and oscillators that produce square waves, sine waves and sawtooth waves.
  (N) Understand how a phase locked loop works.
  (O) Understand the basic principles of basic filter response curves, filter response characteristics, active lo-pass filters, active high-pass filters, active band pass filters, active band stop filters and system applications.
  (P) Explain the Shockley Diode, Silicon Controlled Rectifier, Silicon Controlled Switch, and Diac and Triac, the Unijunction Transistor.
  (Q) Describe the characteristics of light, the operation of photoconductive cells, photodiodes, phototransistors, solar cells, lasers, LEDS, laser diode and the optical couplers.
  (R) Understand the applications of integration of electronic circuits in control systems with sensors for monitoring speed, temperature, humidity, and other parameters.
7. EVALUATION PROCEDURES:
  Unit grades (quizzes) will be averaged along with quick labs, laboratory experiments and final in the following manner:
    All Laboratory  25% of total grade
    All Quick Labs 25% of total grade
    All Quizzes 25% of total grade
    Final 25% of total grade
   

Unit tests are to be graded on an individual basis by the instructor at the end of the formal unit of study.  All tests ate taken in the classroom.  Calculators may be used.  All tests will be considered to have a maximum of 100 possible points.

    Grading Scale
Raw Score Range		 Letter Grade
    100 to 92 A
    91 to 84 B
    83 to 75 C
    74 to 68 D
    67 to   0 F

Special Remarks:

1.

OBJECTIVES: The objectives are enumerated and clearly stated.

2.

TEXT REFERENCES: As annotated in the Lab manual

3.

DISCUSSION: Discussion on the experiment.

4.

PROCEDURE: A detailed step-by-step procedure is given for performing the experiment.

5.

QUESTIONS: A method of asking questions so as to provide a written review of the lesson.  All students are expected to keep up the written work within the laboratory manual.

6.

Materials Required:

All the materials required to do the experiment including test equipment and components are available from the instructor/equipment room.

7.

Attendance:  College policy states that students may be dropped from enrollment when absent 20% of the scheduled class meetings.  If enrolled from the beginning of the term, 15 hours will usually constitute 20% of a four-credit semester course which meets five hours per week.  Reinstatement procedures are described in the PCC catalog.

8.

Tardy Policy:  A student who is late three times (enters classroom after the instructor has taken roll) will be charged with one full absence unless the student can provide valid reasons for one or more of these tardies.

9.

Assignments/Missed Exams:  It is the student's responsibility, whether present or absent, to obtain all material presented and to complete all course assignments.  If prior arrangements are made or extenuating circumstances exist, makeup of tests may be allowed.  Late homework papers will not be accepted unless those same extenuating circumstances exist.  Makeup of quizzes is to be at the instructor's discretion.

8. COURSE OUTLINE
9. METHODS OF INSTRUCTION:
  To be successful in this course, students are expected to participate in discussions, readings, in-class writing, and peer review activities. The instructor may assign point values to such activities.
10. ACADEMIC INTEGRITY:
  The very nature of higher education requires that students adhere to accepted standards of academic integrity. Therefore, Pueblo Community College has adopted a policy of academic conduct as described in the Student Handbook. Violation of academic integrity may be defined to include the following: cheating, plagiarism, falsification and fabrication, abuse of academic materials, complicity in academic dishonesty, and personal misrepresentation. It is the student’s responsibility to be aware of the behaviors that constitute academic dishonesty. Sanctions for violating the standards of academic integrity may include warning, probation, suspension, and/or failure of the course or assignment at the discretion of the instructor.
11. ADA NOTICE:
  Students who have a documented disability may be eligible to receive accommodations for this class. Please contact the Disability Resources Center at 549-3446 for further information.
