CENG 3313 (Linear Circuits) and CENG 3113 (Lab for linear Circuits)

Instructor's Notes; Lab experiments will be available for download on the blackboard.

Electronics lab is an introductory experimental laboratory that explores the design, construction, and debugging of basic electronic circuits. Twelve laboratory projects, involving EDA-tool based simulation and hands-on experiments, investigate the performance characteristics of op-amps, diodes, BJTs, and MOSFETs, including the construction of differential amplifier, summing amplifier, full wave rectifier, common emitter/collector/base amplifier, etc.

Upon completion of this course, students will be able to: analyze electronics devices and circuits using computer simulations; demonstrate understanding of electronic circuits in practical applications; acquire hands-on laboratory experience, utilizing functional generator, oscilloscopes and other modern test equipment; demonstrate proficiency in the use of electronic components like diode and transistor, and equipment; design and perform basic experiments like rectifier and amplifier, and analyze frequency response of amplifiers

Q#1: Measured voltage are different (from Functional Generator to Oscilloscope) A : The default setting for Agilent function generators is to display the desired voltage as though terminated into a 50 Ohm load. When a high impedance device, such as an oscilloscope is used to measure the output of the function generator, the waveform appears to be twice the voltage set on the display of the oscilloscope. We can find the configuration by entering shift then menu (A:MOD MENU) -> three right (D:SYS MENU) -> one down (1: OUT TERM) -> one down (High Z or 50) Q#2: How to read a resister?
A : Please follow the steps below. (Reference)
1) Position the resistor with the gold or silver color band to the right.
2) Read the color sequence that must be decoded to determine resistance. Read the bands from left to right. The colors seen could be any of the following: black, brown, red, orange, yellow, green, blue, violet, gray and white.
3) Determine the coded number for the resistive value. Change the colors to numbers as follows.
Change black to 0.
Change brown to 1.
Change red to 2.
Change orange to 3.
Change yellow to 4.
Change green to 5.
Change blue to 6.
Change violet to 7.
Change gray to 8.
Change white to 9.
4) Determine the tolerance of the resistor. Read the color of the right-most band. A gold band indicates that the actual resistance of the resistor will be within 5 percent of the value indicated by the coding. A silver band indicates that the actual resistance of the resistor will be within 10 percent of the number indicated by the coding. These values are important to calculate the variations that will occur from circuit to circuit randomly as more parts of the circuit are built.
5) Determine the decoded number for the resistive value. You should have a three digit number derived from the color bands. (Your resistor might have four bands in addition to the tolerance band, in this case just write down all four numbers.)
Change the last digit of the coded number to a number of zeros that are to be added to a base value indicated by the preceding numbers. For example, a coded number of 623 would require the addition of 3 zeros to the base value of 62, making the number 62000. If the third band had indicated that 0 zeros are to be added (a coded number of 620), then the number would become 62.
