Solutions Manual Introduction to Mechatronics and Measurement Systems 61 8.1 A digital computer or microprocessor uses digital or discrete data, that is, data that are simply strings of 1's and 0's that have no time correspondence. We have to add some type of time coding to make sense of the data. Therefore we have to design interfaces that will change (convert) analog information into a discretized form that will be compatible with a computer. Again, additional code must be included to provide the time references. 8.2 2*(15 kHz) = 30 kHz 8.3 (a) 1 sample per minute would probably suffice, so f s = 1/60 Hz (b) (c) ± ² ³ ´³µ¶·¸ () ³¹µ¶·¸ º ± ² ³³µ»·¸ ¹µ¶·¸ º
