In a communication system, the signal is represented graphically, whether in a time- domain or frequency-domain style. A signal is represented in amplitude versus time axis in a time-domain representation. The axes in the frequency-domain are amplitude vs frequency. Aside from their axes descriptions, the following is the difference between the two: Select your answer. Oscilloscope is used as a frequency-domain instrument. Oscilloscope is used both as a time- and frequency-domain instrument. Spectrum analyzer is used as a frequency-domain instrument. Spectrum analyzer is used both as a time- and frequency-domain instrument.
Quantization and Resolution
Quantization is a methodology of carrying out signal modulation by the process of mapping input values from an infinitely long set of continuous values to a smaller set of finite values. Quantization forms the basic algorithm for lossy compression algorithms and represents a given analog signal into digital signals. In other words, these algorithms form the base of an analog-to-digital converter. Devices that process the algorithm of quantization are known as a quantizer. These devices aid in rounding off (approximation) the errors of an input function called the quantized value.
