Unformatted text preview: inputs at the same time, recording the mean and standard deviation over a sample size of 10000. Two measurements were made to ensure mitigate the risk of a significant anomaly. All values shown in table 5 have been corrected by subtracting the offset from their respective channels. We can calculate the theoretical value of Vout by simply adding V1 and V2 : Vout = −(V1 + V2 ) = −(6.07 × 10 −3 + 7.11 × 10 −3 ) = −13.18 × 10 −2 V Standard deviation of Vout is calculated in 2 ways. First, the theoretical way of using formula (1) (measured) and second, using error propagation formula (2) (calculated). σ Vsum = σ V1 = σ V2 = 1 σ N - - - - - - (1) N 1 1.19 = 1.19 × 10 −2 V 10000 1 6.49 × 10 −1 = 6.49 × 10 −3 V 10000 σ Vsum = 1 1.29 = 1.29 × 10 −2 V 10000 2 2 σ Vsum = σ V 1 + σ V 2 - - -...
