Analog vs. digital sight and sound we perceive in our natural world are analog info coninuous analog informaion is hard to pick a speciic value must convert to digital. Will allow iner disincion between values cons: *know how much/how many imes to monitor and record data. Digiizaion to convert analog informaion into digital data that computers can handle. Quanizaion during this step, you need to set bit depth. Bit depth refers to number of allowable levels you map (or round) the values to: ex.
