12-1 1. What is the main purpose of an instrumentation amplifier and what are three of its key characteristics? The main purpose of an instrumentation amplifier is to amplify small signals that occur on large common-mode voltages. The key characteristics are high input impedance‚ high CMRR‚ low output impedance‚ and low output offset. 2. What components do you need to construct a basic instrumentation amplifier? Three op-amps and seven resistors are required to construct a basic instrumentation

LDR Circuit Diagram: Here is the schematic for the circuit: Light Dependent Resistors Light Dependent Resistors (LDR) are also called photoresistors. They are made of high resistance semiconductor material. When light hits the device‚ the photons give electrons energy. This makes them jump into the conductive band and thereby conduct electricity. A photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases

consolidating all functions on one chip. This discovery made Intel the early leader of the microprocessor industry. 8008 * The 8008 came out a year after the 4004 as the number of transistors per chip jumped from 2‚250 to 3‚500 and clock rate went from .1 Mhz to .2 Mhz. 8080 * The 8080 was released in 1974 with 5‚000 transistors per chip. It became the foundation of many popular video games that appeared in arcades. With the arrival of the 8080‚ other computer companies could not keep up with Intel’s

depression than the general population. Gluten is also associated with bipolar disorder‚ many believing it being a contributor to the increase in a bipolar patient’s symptoms. Bipolar disorder is a psychiatric condition that causes people to experience extreme mood swings. A group of researchers published a study in March 2012 looking at markers of gluten sensitivity and celiac disease in acute mania‚ a hallmark symptom of bipolar disorder. They found that people

Stepper Motor A stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor’s position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller)‚ as long as the motor is carefully sized to the application. Switched reluctance motors are very large stepping motors with a reduced pole count‚ and generally are closed-loop commutated. Fundamentals of operation DC brush motors

Design and Implementation of a Single Phase Inverter Circuit 1 INTRODUCTION 1.1 Introduction Inverters are used to produce constant or variable frequency AC output from a DC source. These inverters can be used for AC applicatio n like driving an induction motor. Such type of inverters in present world are used largely in renewable energy systems to convert DC to AC‚ example is a PV system where there is a requirement of such type of inverters which can power AC systems such as an induction

Hazards of Electronic waste Electronic waste‚ e-waste‚ e-scrap‚ or Waste Electrical and Electronic Equipment (WEEE) describes loosely discarded‚ surplus‚ obsolete‚ or broken electrical or electronic devices. Informal processing of electronic waste in developing countries causes serious health and pollution problems. Some electronic scrap components‚ such as CRTs‚ contain contaminants such as lead‚ cadmium‚ beryllium‚ mercury‚ and brominated flame retardants. Even in developed countries recycling
