Time Division Multiplexing(TDM): Time Division Multiplexing - Any pulse modulation scheme involves translating the audio, or modulating signal into a series of encoded pulses, sending these pulses over a transmission…
Sensors Based Computer Data Systems: This Sensors Based Computer Data Systems describes hardware/software which is commercially available at several levels of completeness, ranging from single board computer "front ends" to…
Compact Data Logger: Compact Data Logger - A typical unit provides 60 channels of data in a 20 x 40 x 60 cm box weighing about 20 kg. Most manufacturers…
Data Logger Operation: Data Logger Operation - For proper understanding of a Data Logger Operation, it is essential to understand the difference between analog and digital signals. For example, measurement…
DA Converter Working Principle: The resistive divider or ladder can be used as the basis for a DA Converter Working Principle. It is in the resistive network that the actual…
Multi Channel Data Acquisition System: The Multi Channel Data Acquisition System can be time shared by two or more input sources. Depending on the desired properties of the multiplexed system,…
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…
Signal Conditioning of Inputs: Since all the data that have to be acquired, do not generally originate from identical sources, signal conditioning becomes necessary in some cases. A simple attenuator,…
