Question

answer the following questions with an explanation and work out where necessary

 

Question 1 a) Describe the main sources of errors in a measurement process and state how they may be avoided or reduced. b) List two sources of coherent interference and describe how each may be minimized or eliminated. c) An 8-Bit ADC is used to convert an audio signal ranging over 0- 12 v. What is the RMS quantization noise associated with full scale operation of this ADC? d) The circuit of Fig 1.d requires a minimum Output Signal to Noise ratio (SNR0) of 1. i. For the component values shown, determine the SNRO for the circuit given that for the op amp, ena = 5 nV RMS/VHz, and Vs = 100uV, and the circuit is at temp of 300K. (value for constants are on the front page). ii. What practical modification can be made to make SNRO = 1 R1 100K R2 R6 1K OPAMP Vout 5.1k C1 0.01uF 10K RL
