Question

A thermometer measures temperature measurements from -40 to 54.4 degree C. State a universal set to describe temperature measurements. Specify subsets for: Temperature measurements not exceeding water's freezing point, and Measurements exceeding the freezing point but not exceeding 37.8 degree C A random noise voltage al a given time may have any value from -10 to + 10 V. What is the universal set describing noise voltage Hind a set to describe the voltages available from a half-wave rectifier for positive voltages that has a linear output-input voltage characteristic Repeat (a) and (b) if a dc village of -3 V is added to the random noise?

Explanation / Answer

2.

a. The universal set is, S={t:-40<=t<=54.4}.

B. Subset one is S1={t: - 40<=t<=0}.

C. The second subset S2 ={t:0<t<=37.8}.
