How can an analog signal be converted into a digital signal?
ADCs follow a sequence when converting analog signals to digital. They first sample the signal, then quantify it to determine the resolution of the signal, and finally set binary values and send it to the system to read the digital signal. Two important aspects of the ADC are its sampling rate and resolution.
What is requirement for analogue to digital conversion?
For these signals to be used in computing, they must be converted to digital ones. However, digital electronics works in discrete numbers. To convert an analog signal to a digital one, measurements must be sampled at a regular frequency. The sample rate must be at least twice its frequency.
What process must occur to transmit a digital signal over an analog medium?
A digital signal can be transmitted over a dedicated connection between two or more users. In order to transmit analog data, it must first be converted into a digital form. This process is called sampling, or encoding.
How do you tell if a signal is analog or digital?
Most commonly digital signals will be one of two values -- like either 0V or 5V. Timing graphs of these signals look like square waves. That's the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.
