Basic Electronics Analog and Digital

In the oil and gas fields, most electronic equipment such as the transmitter, sensors and control valves are equipped with advanced analog and digital electronic modules to perform various tasks such as signal conditioning & filtering, adaptation of impedance, analog to digital conversion, data transmission, and signal processing and recognition. This requires an adequate processor which can be either a microcontroller, a microprocessor, or digital signal processor (DSP) to coordinate and handle these set of tasks, in addition to some other electronic circuits such as amplifiers, filters, analog switches, and modems to adequately preprocess the noisy input signals.

The purpose of this course is to teach various analog and digital electronics circuits used in now a day’s electronic equipment targeting oil & gas industry. On the shelf processor from a leading semiconductor company (e.g., HCS12 microcontroller from Motorola) will be addressed from both the hardware and software programming points of views. In order to let the audience properly grasping the theoretical aspect of the course, practical hands on sessions may be conducted to design various digital and analog electronic circuits.

Course Objective

The main objective of the course is to be acquainted with fundamentals of electronics (analog and digital electronics) which are required in various electronic equipment (e.g. instruments, actuators, and telemetry systems) deployed in oil and gas fields. Practical hands on sessions may be conducted to design various analog and digital circuits.
