• Analog to Digital Conversion: Sampling Rate ✔✔how many times a digital sample is taken of the analog sample, per second Ex. CD Sampling rate = 44.1kHz Called Pulse Code Modulation (PCM) De... termines digital signal's accuracy Nyquist-Shannon Sampling Thm ✔✔• Analog sig must be encoded at rate 2X or more than highest freq. of sample • Human hearing is up to 20kHz -> digital audio should be at least 40 kHz o Bit depth ✔✔Number of bits used to describe a sampled voltage level -> "quantization" Assigns quantity to the signal being measured Greater bit depth = more accurate rep of signal • i.e. if sig has on bit -> 0 or 1-> describes only two states, on or off • 2 bits= 4 states • CD has 16 bits -> 216 [Show More]
