Your design of the mechatronics system should include atiler to suppress the noise. (c) For the sample & hold amplifier, besides a buffer amplifier and a switch, the other major component is

Explanation / Answer

(A) Here Buffer Amplifier has been used for Impedance matching purpose. Sensor posses low output impedance and Low Pass Filter posses High input impedance. Therefroe to avoid loss of voltage signal buffer is used.

(B) Narrow Pass Filter with center frequency of 60 Hz can be used.

(C) Other major component must be quantizer before sample and hold circuit.
