Unformatted text preview: Tolerance is the acceptable deviation from a target value, or the range of acceptable limits with respect to a target value. externally imposed. Analog signals after digitization (sampling +quantization) are processed by digital systems. The Nyquist Theorem specifies that no analog signal must have frequencies greater than half the sampling frequency. Fmax<=0.5 SF. Analog inputs converted to digital values are subject to quantizing error. Multiplexing-MUX is an essentially an Electronic Switch using which the computer reads information from various channels one at a time Potentiometer is an a variable voltage divider-.used for measurement is a type of bridge circuit for measuring voltages by comparison between a small fraction of the voltage V0=(x/L)Vs tachometer is a device that measures angular velocity....
