A differential amplifier is very useful for removing common mode noise voltage that might be fed or induced in the signal cables
. Suppose the input signal coming from a signal wire is Vs. Because of potential corruption in the measurement circuit, a common mode noise Vn is induced. In this case, the input voltages at both input wires become Vs Vn at the inverting input and Vn at the non-inverting input. Derive the circuit transfer equation and give the condition for removal of common mode noise.

C both A and b cause they are technician both technicians so they both measure out the floor pan reinforcement be designed to transfer collision energy so I say both A and B
