Homework 4 - Signal Generation
Problem 1.
Using a 20MHz crystal with a negative temperature coefficient of k = -8Hz / Mhz / deg C,
determine the frequency of operation for temperature changes of (a) an increase of 10
deg C, (b) an increase of 20 deg C, (c) a decrease of 20 deg C.
{ Solution }
Problem 5.
