A voltage-representation signal, which is proportional to a voltage across a heater component, is received. A magnified voltage-representation signal is generated by determining a difference between a voltage baseline offset, which represents a minimum operating voltage of the heater component, and the voltage-representation signal. A current-representation signal, which is proportional to an electrical current passing through the heater component is received. A magnified current-representation signal is generated by determining a difference between a current baseline offset, which represents a minimum operating current of the heater component, and the current-representation signal. The magnified current-representation signal is modulated to generate a resistance-representation signal that is proportional to an amount of modulation that makes the magnified current-representation signal approximately equal to the magnified voltage-representation signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Resistance determination with increased sensitivity for temperature control of heated automotive components","description":"Electrical resistance of a heated component is determined for temperature control and monitoring.
