Basic Introduction to Digital Filter [Video]
23 October 2020
A Digital filter is an algorithm or device composed of a digital multiplier, adder, and delay unit. The function of the digital filter is to perform arithmetic processing on the digital code of the input discrete signal to achieve the purpose of changing the signal spectrum. The method of the digital filter to filter the signal is: use a digital computer to process the digital signal, and the processing is to calculate according to the pre-programmed program.
Introduction to Wireless Sensor Networks
20 August 2020
The component modules of the wireless sensor are encapsulated in a shell. When it is working, it will be powered by a battery or a vibration generator to form a wireless sensor network node. It consists of randomly distributed micro nodes integrated with sensors, data processing units, and communication modules. The way of self-organizing constitutes a network. The wireless sensor network system usually includes sensor nodes, sink nodes, and management nodes.
