    ...TD and TA are given in milliseconds by algorithms 1 and 2. Both are simple algebraic algorithms, on which the independent variables are the distance between predefined "R" peaks, and gender (Male or Female). The EKG signal is provided by a BIOPAC 100 Amplifier. Because we are in different countries, please elaborate how the Quality Control will be done. A more detailed specification will be given once we agree in pricing and delivery time. The project is simple, but requires experience in Real Time signal processing. A BIOPAC 100 Amplifier provides an EKG analog signal that can be regulated until 10 Volts. What is needed is to detect the "R" peak of the EKG waveform. After a time delay higher than 85 milliseconds, a Linear actuator is activated to ...

Explore the differential amplifier characteristics of gain and impedance in both differential and common mode, and the common mode rejection ratio (CMRR), then add current source biasing and an active load. You will then add an output stage to make the two-stage op amp. The final step will be to add an improvement of your choice. For maximum CMRR, the differential pair transistors should be as identical as possible. Instead of discrete transistors, we will use the MPQ3904 array, which has four npn transistors on one chip. Later, for the active load you will also need two matched...

    Trophy icon Design a Rock’n Roll suitcase Encerrado left

    This project is to design a suitcase or a briefcase that immediately reminds you of those beautiful vintage guitar amps. The case should use the form language of vintage guitar amps. It actually CAN look like a true guitar amplifier, but it doesn’t have to. Your solution can as well just reflect the design ideas that are typical for this kind of devices. The challenge is to use those typical elements without overloading the case. The proportions of the case can be anywhere between a rather slim briefcase (for your next meeting) and a more „bulky“ suitcase (for your dancing shoes, beer cans or whatever). If you find a design solution that can be used for anything between briefcase and suitcase - so much the better. The pictures show our prot...
