Digitaalmõõtmised

Digitaalmõõtmised refer to the process of converting analog signals or physical quantities into a digital format that can be processed, stored, and transmitted by computers. This conversion is fundamental to modern technology and is employed in a vast array of applications. The core of this process involves an analog-to-digital converter (ADC), which samples the analog signal at regular intervals and quantifies its amplitude into discrete numerical values. The resolution of the digital representation is determined by the number of bits used to encode each sample, while the accuracy of the measurement is influenced by factors such as the sampling rate and the precision of the ADC itself.

The advantages of digital measurements are numerous. They offer greater precision and accuracy compared to many analog counterparts, are less susceptible to noise and interference during transmission, and can be easily manipulated and analyzed using software. Digital data can be stored indefinitely without degradation and shared globally with ease. This has revolutionized fields like telecommunications, scientific research, medical imaging, and industrial automation. Examples of digitaalmõõtmised include digital thermometers, digital multimeters, and the audio and video signals captured by digital cameras and microphones. The ongoing miniaturization and increasing power of digital processing continue to expand the possibilities and applications of digitaalmõõtmised.
