Definition of "digitization" |
Digitizing or digitization is the representation of an object, image, sound, document or a signal,usually an analog signal by a discrete set of its points or samples. The result is called digital representation or, more specifically, a digital image, for the object, and digital form, for the signal. Strictly speaking, digitizing means simply capturing an analog signal in digital form. For a document the term means to trace the document image or capture the corners where the lines end or change direction. / Transconductance is the property of certain electronic components. Conductance is the reciprocal of resistance; transconductance is the ratio of the current change at the output port to the voltage change at the input port. / a process applied to a continuous quantity that samples the quantity first, say, in time or spatial domain, and then quantizes the sampled value. For instance, a continuous-time signal can be first sampled and then quantized to form a digital signal, which has been discretized in both time and magnitude. |
