  • 9. Analog VS Digital Computer Normal (Human & Animal)Voice is Analog Signal. Vibrations are Analog Signal. Needed devices to convert analog signal to digital signal. Computer can operate and store only in digital data. But it can convert analog to digital and vice versa. Simple example for a digital data is normal switch which can be operated in any one of the two states(ON / OFF) There are some hybrid computers which can operate in Analog as well as digital data like Medical Scanners etc.,        9 SysKan TechnoSoft +91-9944159844
