To start with we may have thousands of sample valuesīut we may want to retain only a few hundreds of Sample values that can be used to represent a digital Quantization levels refers to the number of different The highest frequency you want to capture. This theorem states that the sampling rate on analog-to-ĭigital conversions must be at least two times the value of The wave can be more more difficult it is to closely The wave cannot be matched shape of the wave also cannotĪt a higher sample rate However, the higher theĪnd bit depth, the shape of frequency of the sound, the Line equals one sample) and the Y axis represents bit depth.Īt a low bit depth, the shape of At a low sample rate, the In the diagrams below, the X axis represents sample rate (each Wave, and higher bit depths allow the analog shape to be more Each sample measures the amplitude (shape) of the It determines the quality of output signalīit Depth refers to how much information is captured with a Rate or sampling frequency, and denotes the number of sample Rate of frequency at which sampling occurs is known as sampling Representation of the original analog signal.
Sampling is the process of converting a continuous analog signal to aĭiscrete analog signal and the sampled signal is the discrete time Analog to Digital conversion takes place in 3 steps:-ġ] SAMPLING: which measures the amplitude ofĢ] Quantization: is the process of rounding of theģCode word generation: finally converts the signal
