The output of this LVDT is fed to an amplifier with voltage gain of 5. The output of amplifier is connected to an 8 bits ADC with V 5V. The LVDT supply (excitation) voltage level is chosen as given in the specifications with frequency of 3 KHz. Answer the following: (b) Make functional block diagram of the complete system and write transfer functions of each bullding block. (c) is complete dynamic range of ADC being used? Justify your answer. (d) What is the sensitivity of LVDT selected in sub-para (a) above? Also draw input outpe graph of the LVDT in our system. (e) Determine the output of LVDT when output of ADC is (C8) (1) Evaluate resolution of the overall system.
