Question

6.5A sinusoidal signal is transmitted over a noisy transmission link to a remote correlator acting as a receiver. Figure Prob. 5 shows a typical autocorrelation function. Use the figure to estimate the following quantitics: (a) Signal power (b) Noise power (c) Signal-to-noise ratio in decibels (d) Signal amplitude (e) Signal frequency (f) Noise standard deviation (assume zero mean) Hint: use eqns (6.27) and [6.33 124 SIGNALS AND NOISE IN MEASUREMENT SYSTEMS Figure Prob. 5. 12 10 Time delay β ms 12 14 -2 -4 138
