    1. We wish to sample a small signal that is on top of a large DC offset using a DAQ (Digital Acquisition System such as your nscope) that has a limited input voltage range of ±5 V. If the signal is modeled as Vin-0.1sin(ot)+10 V where 0.1sin(ot) V is the signal and 10V is the DC offset, design a circuit using two op-amps that first removes the DC offset then amplifies the signal by a factor of 40. 2.

    Problem #1 A large warehouse has five temperature sensors located in five different places. Each sensor circuit is indicated as the figure below, where a DC current source circulates through a temperature-variable- resistance. Tk is the temperature in Celsius at the sensor in a given location; Tref is the reference temperature that each sensor has been calibrated. Assume for this problem that Tref 27 °C. Therefore, each sensor will provide a positive-voltage for temperatures greater than the reference, on the...
