can you help me do this?
A thermoelectric-based power meter has a response time of 20 s and sensitivity (output voltage per unit incident power) of 90 mV/W. If the time response is reduced to 8 s by increasing the thermal conductance between the sensor element and heat sink, what will be the new sensitivity?

Build an Op-Amp Circuit Network. Note you only have a power source of 5V available. You have a voltage signal that latches at a constant 1.5V. Create a difference circuit to produce an output voltage of 2V. Put P/Ns and element values in your design. Show your work. From part a)’s output voltage, assign that now as a reference voltage (Vref) to compare to an analog sensor signal (Vin) that can range between 0V – 5V. Make sure your circuit...

Question:
In this quiz, you will examine the behavior of a simple motor speed con- trol system. Figure 1 shows the block diagram of the entire control loop Without covering the details, the motor is approximated by two equations First, the current through the motor coils (IM) creates a magnetic torque TM. We consider an external load D(s) (i.e., the disturbance) that subtracts from this torque. The difference accelerates the rotational inertia J of...
