Resources to mark the 100th day of school with math activities. Challenge students to generate 100 different ways to represent the number 100. Students will easily generate 99 + 1 and 50 + 50, but encourage them to think out of the box. Challenge them to include examples from all of the NCTM Standards strands: number sense, numerical operations, geometry, measurement, algebra, patterns, data analysis, probability, discrete math, Create a class list to record the best entries. Some teachers write 100 in big bubble numeral style and then record the entries inside the numerals.

Many systems involve some type of time keeping. By using 555 integrated circuit in astable state it is easy to design and make accurate and cheap timing circuit (e.g., alarm circuit, counting circuit, sensing circuit, etc.) The working principle of this 555 IC in astable state is supported by the following formulae: Timing period, Timing=(R1+2R2) C/1.44.

An introductory course in analog circuit synthesis for microelectronic designers. Topics include: Review of analog design basics; linear and non-linear analog building blocks: harmonic oscillators, (static and dynamic) translinear circuits, wideband amplifiers, filters; physical layout for robust analog circuits; design of voltage sources ranging from simple voltage dividers to high-performance bandgaps, and current source implementations from a single resistor to high-quality references based on negative-feedback structures.

Take a hands-on ride through the fundamentals of electronics and acoustics, and the process of loudspeaker design and construction. Learn about the engineering and art involved throughout music/movie recording and playback, the design and application of everything from microphones to DACs, amplifiers, and speakers. With the aid of computer assisted audio measuring equipment at the MIT Edgerton Center, analyze the frequency response and distortion of speaker drivers, and understand their effect on what we hear. Design your own speakers - driver selection, crossover networks, and enclosure design - and build them in class!

In this simulation you will investigate relationships between voltage, resistance, and current that exists in an electric circuit. You will adjust voltage of the power source and resistance of the resistor and then use digital multimeter to obtain measurements. Then you will record these measurements and look for relationships that exist between voltage, resistance, and current.

This course covers sensing and measurement for quantitative molecular/cell/tissue analysis, in terms of genetic, biochemical, and biophysical properties. Methods include light and fluorescence microscopies; electro-mechanical probes such as atomic force microscopy, laser and magnetic traps, and MEMS devices; and the application of statistics, probability and noise analysis to experimental data.

A short description of the workings of an op-amp

You can build a wide range of practical electronic devices if you understand a few basic electronics concepts and follow some simple rules. These devices include light-activated and sound-activated toys and appliances, remote controls, timers and clocks, and motorized devices. The subject begins with an overview of the fundamental concepts, followed by a series of laboratory exercises that demonstrate the basic rules, and a final project.
