Hall Effect is a technique of the measurement of the voltage that is transverse. It was proposed by Edwin Hall in the year 1879. The purpose of this effect is to study the behavior of the current carried in the respective conductors present in the circuits. It is also used in various application sensors such as pressure sensors, current sensors, etc… For the measurement of the intensity of the magnetic field in the circuit, hall effect sensors are utilized. The measurement of this magnetic fi … [Read more...]
What is an Adaptive Delta Modulation & Its Working
Delta modulation is basically analog to digital and a digital to analog signal conversion technique which is mainly used for data transfer. This type of modulation technique is used by the satellite business system, and it is also known as Differential pulse code modulation. This modulation technique is used to achieve high signal to noise ratio. Delta Modulation is basically of three types that are Adaptive Delta Modulation(ADM), Delta-sigma Modulation, and differential modulation. The ADM is a … [Read more...]
What is a Rheostat : Working & Its Applications
In an electric circuit many times it is desirable to restrict the current, which can either be done by reducing the voltage or increasing the resistance in the circuit (Ohm’s Law). A rheostat is a device that facilitates this. The word rheostat is derived from the Greek language meaning changing stream (current). It is a must for any electrical laboratory/workshop in order to carry out experiments under variable current and voltage conditions. This is done by inserting a variable resistance in t … [Read more...]
What is an RC Oscillator : Circuit & Its Working
An oscillator is used to produce periodic oscillating signals in an electronics circuit. The oscillations are mainly produced in the form of a square wave or sine wave. The oscillators can convert DC to AC and used in a number of electronic devices like clock generators, digital instruments like calculators. The oscillating signals are used in television transmitters, wall clocks, radios, and many more. A feedback oscillator is a type of oscillator in which the output signal is feedback into the … [Read more...]
What is an Isolation Amplifier : Working & Its Applications
Sometimes, while performing electrical operations, it becomes important for us to isolate one part of the circuit to another to prevent excess loss of energy. For that reason, we use an isolation amplifier which acts as an isolating device. The main purpose of the isolation amplifier is to electrically separate the circuit which comes before the amplifier from the circuit which comes after the amplifier. So, basically we can say that an isolation amplifier can be used to give ohmic isolation … [Read more...]
What is a Gyroscope Sensor : Working & Its Applications
MEMS or Microelectromechanical systems are basically microsystems that have a very small size. It is an extremely advanced form of technology that has given rise to different electronic components like accelerometer and gyroscope sensor. An accelerometer is a device that can be used to detect non-gravitational motion. A gyroscope sensor, on the other hand, can be used to detect gravitational motion. Thus, we can see that a gyroscope sensor and an accelerometer complement each other. Both of … [Read more...]
What is Touch Sensor : Working & Its Applications
Even if a human body touches something, instantly the surface information will be passed to the brain using senses. Touch can also be felt by animals and plants. Hence the same technique can also be implied in today's electronics. Electronic devices consist of various sensors like temperature, pressure, humidity, etc. Similarly, a sensor related touch device is also designed. Nowadays, we are coming across the user interfaces that are operated on a single touch. There is a wide range of … [Read more...]
