Free Essays on Analog to Get Inspired & Learn by Example

Analog and digital signals, basically, differ in their graphs of voltage versus time. Analog signals have a continuous signal function with respect to time (Angoletta, 2014). The signal here can be sound, light, temperature, pressure, etc. The signals have smooth continuous changes similar to an analog watch. On the other hand, digital signals have a discrete (taking only binary values 0 and 1) function with respect to time. The signals have determined levels such as the case of the digital clock where time can only take account of 0 to 9.
The advantages of using analog versus digital signals Continue reading...

Introduction
It is a part of the job of an energy manager that he minimizes the energy loss of the building by controlling the ambient temperature of the building or different parts of the building. In order to maintain the temperature and save valuable energy, a data acquisition and monitoring system is needed that will display the ambient temperature with the help of sensors. This supervisory control system will be designed to control the remote infrastructure that handles the heating system. The energy manager will be in control of this system. First the data of the room will be Continue reading...
