a) Negative feedback circuits such as the Schmitt trigger are used to solve noisy scenarios in comparator circuit applications. Using circuit diagrams and waveforms, explain clearly how this is achieved. b) An LM35 temperature sensor has the following transfer function: Vout 10mV °C x Temp (°C) Design an electronic circuit to turn on an LED rated at 5V whenever the temperature falls below 85°C. The circuit should use a comparator, a few resistors and the LM35 temperature sensor. You should demonstrate by calculation and by simulation in multisim or proteus that your circuit works correctly. Only screenshots are required for simulation no files needed.

Please let me know what you get.

Please show all work

H.W: Derive the following and draw the circuit. ⚫ The output voltage of the summation Op-Amp. ⚫ The output voltage of the subtractor Op-Amp.

An op-amp comparator in a firing circuit can produce waveforms at the output of up to 28 V peak-to-peak without any distortion. An inverse cosine-based firing circuit with a voltage range from +14 to -14 (reference voltage) is used to produce a gating signal for the SCR at the desired delay angle. if the reference voltage is 5.92 volts, the delay angle (in degrees) would be: O A. -155 O B. None of the other choices are correct O C. 155 O D.-25 O E. 65
