Three point tracking is achieved by __________(a) Double conversion(b)

1.	Three point tracking is achieved by __________(a) Double conversion(b) Variable selectivity(c) Variable Sensitivity(d) Padder capacitorI got this question by my college director while I was bunking the class.The doubt is from Comparison Between PM and AM in division Noise of Analog Communications
Answer» Correct option is (d) Padder capacitor To EXPLAIN I would SAY: To achieve three point tracking a capacitor is connected in series with LOCAL oscillator coil. This capacitor is CALLED padder capacitor.
