linear applications because they believe that the gainsthat can be realized by MOSFET amplifiers are too low to bother with. 3,4 However, if they arecarefully biased and utilized at frequencies below 100KHz, gains from a MOSFET amplifier canpractically approach 50 while offering much higher input impedances, as mentioned above. Thisis possible because the gain parameter of a MOSFET, its transconductance (yfs), is a function ofits bias point (Q point). In contrast, the current gain function of a BJT (hFE) is approximatelyconstant over most its range of bias points, relative to a MOSFET.Practical MOSFET Amplifier DesignProblem Definition and Design ConstraintsGiven a specific input voltage (Vi = 50mVp which is the approximate output amplitude of

The course is completely online, andstudent-teacher interaction comes primarily from Q&A discussion boards (Piazza) and one liveQ&A session per week (WebEx). The course revolves around a semester-long project in whichstudents develop a mini e-commerce web application complete with the design andimplementation of the web interface, the database, and the application business logic.In this paper, we talk about how the course evolved when the developer joined the educator toteach the course. We focus on six important facets of the experience: (1) the initial conditionsthat allowed the collaboration to be successful, (2) the

-based demonstrations previously mentioned. This new board interconnects aTexas Instrument (TI) C6711 or C6713 DSP starter kit (DSK) to an Analog Devices (AD)quadrature modulator (AD9857). This modulator is capable of operating at up to 200 millionsamples per second (MS/s), with a resulting carrier or intermediate frequency of up to 80 MHz(i.e., 40% of the system’s sample frequency). An onboard 32-bit direct digital synthesizer (DDS)is used to generate the carrier waveform values. Baseband 14-bit in-phase and quadrature (I/Q)data are presented to the modulator, which can be programmed to interpolate the data at rates of4x to 252x. The AD9857 is interfaced to the DSK using an Altera Cyclone FPGA. The FPGAprovides queuing of the I/Q data, and the

For example, logarithmic scoring holds thepossibility of an infinitely negative score. While this may seem like a defect, we will argue thatthis feature is a benefit of log scoring. Any linear

The user was not required toaccess these investigation screens in order to perform a test simulation.

Students’ perception on the learningenvironment was measured using the Supportive Learning Environment for ExpertiseDevelopment Questionnaire (SLEED-Q) [1]. The SLEED-Q was administered to students in Fall2018 and Fall 2019 (normal instruction) and compared with responses obtained from Fall 2020(remote instruction).

A deductive calculuspresentation of differentiating v0 with respect to flight time would belong to the academiclearning approach2, which is teaching time efficient for those students very familiar withcalculus.

For QPSK modulation, the values are multiplexedinto parallel I and Q output streams of even and odd bits.The receiver section performs the reverse operation. A phase locked loop extracts a clock fromthe incoming digital bit stream(s). For BPSK, a single incoming bit stream is converted to8-bit parallel values. For QPSK, two bit streams are first recombined into a single stream andthen parallelized. The parallel

robotwas used for about 25 years to teach undergraduate engineering students robotics concepts andapplications. Originally, the robot’s controller was connected via a 9-pin serial port to an Intel8088-based PC. The PC communicated with the robot via Q-Basic programming language runningunder the Disk Operating System (DOS). One group of students was exposed to two phases ofdevelopment, DosBox and MATLAB environments running in Windows 7 64-bit. Students’attitudes and perceptions surveys, students’ self-reflections statements, and individual studentinterviews, strongly indicated that the old robot with an upgraded computer environment is still acapable tool in developing industrial robotics programming skills.IntroductionIndustrial robots are an

When these equipment are not readily available, simulation software often provides an alternative way of studying the fiber optic communication systems. In this course, OptiPerformer was selected to study the performance of fiber optic communication systems 4. This category includes two activities: a.
