In other words, one variable is an analog of the other. Mini computer is a computer that has the same functionality as large computers but appears in a smaller size. Unlike passive protection, DSP suppresses noise without blocking the speech signal. /Subtype /Image The word digital comes from the same source as the words digit and digitus (the Latin word for finger), as fingers are often used for counting. An analog signal is represented by a sine wave. x1O0OBmREUTTY6* A micro computer is a small, relatively inexpensive computer with a microprocessor as its CPU ( Central Processing Unit). There are four possible combinations of data and signal types: Analog data, analog signal; Digital data, analog signal; Analog data, digital signal; Digital data, digital signal.

Digital Signal Processing is important because it significantly increases the overall value of hearing protection. It differs from a digital signal in terms of small fluctuations in the signal which are meaningful. Privacy. Signals Classification Continuous Time and Discrete Time Signals. An analog signal is more prone to distortion in response to noise, but a digital signal has immunity in response to noise hence it rarely faces any distortion.
An analog or analogue signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal. Examples: Any natural sound, human voice, data read by analog devices.
