PROGRAMMING IN C AND C++

Design, code, and test C++ programs of moderate complexity.

• Implement dynamic data structures, e.g., linked lists and queues, in C using the enum and struct data types and the functions malloc (), calloc (), and free ().
• List at least three advantages of the object-oriented approach to software design.
• Describe and demonstrate the implementation and operation of:
• State the meaning and describe the use of the C++ keywords private, public, and protected.
• Describe the operation of constructor and destructor functions in C++.
• Describe and demonstrate the use of the this pointer.
• Explain and demonstrate the use of base class and member initializer lists in constructor functions.
• Use the C++ new and delete operators to allocate and free memory for dynamic objects.
• Describe and use the basic principles of hierarchy and inheritance in object-oriented programming.
• Describe and demonstrate the relationship between base and derived class objects in terms of access to public, private, and protected members.
• Describe and demonstrate the use of pointers to obtain access to members of base class and derived class objects in C++.
• Describe and demonstrate the use of virtual functions in C++.
• Use the concept of composition (the inclusion of objects of existing classes as member data in higher-level classes) in object-oriented design.

TRANSDUCERS AND SIGNAL CONDITIONING

Design appropriate signal conditioning amplifier and anti-aliasing filters for a given application.

• Determine the requirements for the interface between a given transducer and measurement system.
• Derive the system equation, transducer equation, and signal-conditioning amplifier equation for a given transducer and measurement system.
• Design, build, and calibrate an appropriate signal-conditioning amplifier to interface a given transducer and measurement system, taking into account transducer loading error and gain-bias interaction.
• Define the following characteristics of real op-amps and describe their effect on signal-conditioning amplifier design:
• Offset voltage;
• Bias current and offset current;
• Drift
• Common-mode rejection ratio
• Power-supply rejection ratio
• Bandwidth
• Slew rate
• Design precision voltage references based on Zener diodes and integrated circuit references.
• Design two- and three-op-amp instrumentation amplifiers and describe their characteristics.
• State the Nyquist sampling theorem. Define aliasing, and describe its effect in a sampled-data system. Select or design an anti-aliasing filter appropriate to a given system.

NETWORKING WITH TRANSMISSION CONTROL PROTOCOL/INTERNET PROTOCOL (TCP/IP)

Design a simple TCP/IP application using a standard socket library.

• Define the Internet Reference Model and its relationship to the ISO-OSI seven-layer model.
• Describe the IP addressing scheme.
• Translate IP addresses from binary to dotted-decimal notation and vice versa.
• Determine the network class of a given IP address.
• Describe the purpose and use of special IP addresses.
• This network address
• This host address
• Loopback address
• Broadcast addresses
• Non-routable addresses
• Differentiate between IP and TCP/UDP (User Datagram Protocol) with reference to the concept of encapsulation.
• Describe the purpose of a network router.
• Describe the purpose of each of the following TCP/IP applications.
• File Transfer Protocol (FTP);
• Telnet;
• Hypertext Transfer Protocol (HTTP).
• Define the terms 'port' and 'socket' in the context of TCP/IP networking.
• Implement a simple telnet interface to an embedded control system.

USER INTERFACE DESIGN

Implement a graphical user interface to an embedded control/data acquisition system by means of HTML web pages.

• Describe the basic architecture of a web browser and the interaction between browser (client) and server under Hypertext Transport Protocol (HTTP).
• Use Hypertext Markup Language (HTML) to construct simple web pages including: headings, text, images, lists, and links to other pages.
• Use HTML forms to implement standard graphical user interface (GUI) selection techniques, e.g. buttons, radio buttons, and check boxes.
• Use HTML methods (GET and POST) to transfer files between client and server.
