Unformatted text preview: 0.1 ° C temperature resolution between 0 ° C and 25 ° C? Assume that the resistance in this temperature range follows a power dependence: R th = 33k Ω× 1.049 –T/ ° C with temperature T expressed in degrees Celsius. To achieve 0.01 ° C resolution? 2. Show how to use the 555 timer to make a frequency divider, i.e. a circuit that accepts a square wave as input and outputs another square wave of a lower frequency (Hint: 555 in monostable configuration). Implement a divide-by-three circuit in LTspice. The input wave is to have a frequency of 30 kHz. Printout your schematic and the traces of input, output, and threshold voltages. Explain how the circuit works. 3. Digital capacitance meter. Lab Manual, Chapter 10, Practice problem 3....
