Post lab A write-up of this exercise should include; a) A comparison of the beam data with expected theoretical values. b) A comparison of the FFT data with expected theoretical values. c) A specification for the FIR filter and supporting measurements. Compare your filter performance with the RC filter described in this guide. d) A calculation of the Q value obtained for the tuning fork filter and a comparison of this value with the Q obtained for the Wien bridge filter from the previous lab. e) Evaluation and discussion the errors inherent to the measurements.
