Ya its manual input device
The difference is that an Non-Automated Input Device is used when the user is the source of input (e.g the data will be typed in or draw by the user), while Automated Input Devices are use in situations where the data is already prepare in a form which the input device can pick up and transmit directly into the computer.
It is an device that does not need a human to interact with to work correctly
Form of modulation that represents digital data as variations in the amplitude of a carrier wave Follow this link to get exact idea of Amplitude Shift Keying (ASK) http://www.circuitsgallery.com/2012/05/binary-amplitude-shift-keying-bask-or.html
A manual system analysis require individuals to supply input directly into a system designed to simulate real life events. An automated system is controlled by technology to automatically supply input.
Its fairly self explanatory, put the input IN then check the output at the OUTPUT.
Boundary Value Analysis
In FSK the output frequency is dependent on the input bit stream. Here 2 (for Binary FSK) different carrier frequencies are used and they are switched according to input bit stream. When input is at logic1 output is freq. f1 and when input at logic0 output is freq. f2, where f1 and f2 are different.
Automated input devices are more accurate because there is a decreased chance of human error due to the following factors; computers never get tired, they are not biased in any way and more accurate calculations can take place quickly and repetively. The same task can be performed with 100% efficiency.
Gate diffusion input is defined as the new technique of low power digital combination of circuit design. This allows reduced power consumption and delayed propagation.
An input device is any device that enables feeding of information into a computer, including office data entry devices. An office data entry device is one that is purely used for keying in data into a computer e.g. a mouse and a keyboard.
