Schering bridge

 Schering bridge

It is one of the most widely used bridges for the measurement of unknown capacitors, dielectric loss and power factor.
It can be used for low voltages. The Cx is the perfect capacitor to be measured. Rx is series resistance. C2 is a standard air capacitor with having very stable value. R3 and R4 are noninductive resistances while C4 is a variable capacitor.

Analog to Digital Converters: Successive Approximation A/D Converter

  Analog to Digital Converter & Its Working Almost every environmental measurable parameter is in analog form like temperature, sound, pressure, light, etc. Consider a temperature  monitoring system  wherein acquiring, analyzing, and processing temperature data from sensors is not possible with digital computers and processors. Therefore, this system needs an intermediate device to convert the analog temperature data into digital data in order to communicate with digital processors like microcontrollers and microprocessors. Analog to Digital Converter (ADC) is an electronic integrated circuit used to convert the analog signals such as voltages to digital or binary form consisting of 1s and 0s. Most of the ADCs take a voltage input as 0 to 10V, -5V to +5V, etc., and correspondingly produces digital output as some sort of a binary number. What is Analog to Digital Converter? A converter that is used to change the analog signal to digital is known as an analog to digital...

Single Channel Vs Multi Channel DAS

  Single Channel Data Acquisition System: A Single Channel Data Acquisition System consists of a signal conditioner followed by an analog to digital (A/D) converter, performing repetitive conversions at a free running, internally determined rate. The outputs are in digital code words including over range indication,  polarity  information and a status output to indicate when the output digits are valid. A Single Channel Data Acquisition System is shown in Fig. 17.3. The digital outputs are further fed to a storage or printout device, or to a digital computer device, or to a  digital computer  for analysis. The popular Digital panel Meter (DPM) is a well known example of this. However, there are two major drawbacks in using it as a DAS. It is slow and the BCD has to be changed into  binary coding , if the output is to be processed by digital equipment. While it is free running, the data from the A/D converter is transferred to the interface register at a rat...

DSO & MSO (Block Diagram)

DIGITAL STORAGE OSCILLOSCOPE (DSO) The digital storage oscilloscope eliminates the disadvantages of the analog storage oscilloscope. It replaces the unreliable storage method used in analog storage scopes with digital storage with the help of memory. The memory can store data as long as required without degradation. It also allows the complex processing of the signal by the high-speed digital signal processing circuits.  In this digital storage oscilloscope, the waveform to be stored is digitised and then stored in digital memory. The conventional cathode ray tube is used in this oscilloscope hence the cost is less. The power to be applied to memory is small and can be supplied by small battery. Due to this the stored image can be displayed indefinitely as long as power is supplied to memory. Once the waveform is digitised then it can be further loaded into the computer and can be analysed in detail. Block Diagram As done in all the oscilloscopes, the input signal is applied to the...
