The paper speed used with EFM in North America is: a. 1cm/min b. 2cm/min c. 3cm/min - C. 3cm/min The US transducer on the EFM measures the a. Electrical signal of the fetal heart b. Mechanical movement of the fetal heart reflected off of sound waves c. R to R intervals of the fetal heart - b. Mechanical movement of the fetal heart reflected off of sound waves The purpose of the autocorrelation in external monitoring is to a. Compare incoming waveforms for comparison b. Decrease signal...

The Autocorrelation Function (ACF) Questions with complete solution 2023/2024The j-th order autocorrelation function is defined as - correct answer rho(j) = gamma(j)/gamma(0) = ([E(X(t)-mew)*E(X(t-j)-mew)])/(E[(X(t) - mew)^2]) = (Cov(X(t),X(t-j))/Var(X(t) for j = 0,1,2,... with -1 <= rho(j) <= 1 The plot of rho(j) against j = 0,1,2,... is called - correct answer the correlogram For a stationary ergodic process, the ACF can be estimated by the sample moments as follows - corr...
