Consider a 12 -bit ADC and full scale voltage measurement rangeof –12V to + 12V. Find the resolutionand % error.[2 Marks]CompareLED and LCD. (any for points) [2 Marks] Various parameters ofSchering bridge are given as follows. The voltage supply of 2 kHzis connected toterminals A and C and detector to points B and D.ArmAB comprisesthe unknown Resistor R1 and capacitor C1. Arm BCconsists of resistor R2 of 18k Ω. Arm DA consists of capacitorC2of0.06 μf.Arm CD has R3 of 1.5kΩ and C3 of2nf arein parallel.Calculate(i) the capacitance (C1)(ii) the equivalent seriesresistance (R1) and(iii) dissipation factor. Also draw theschematic diagram.
