Consider the following signal: v(t) = A + B sin(27fbt) + C cos(2nfct) + D sin(27 fot) where A = 2.7 V, B = 3.7 V, C = 1.0 V, D = 2.3 V, fb = 1.9 kHz, fc = 3.4 kHz, and fd = 4.1 kHz. Using an oscilloscope, you measure the signal directly in the time domain. What sampling resolution is required for the oscilloscope measurement to accurately determine the signal spectrum via a Fourier transformation of the time-domain measurement? Give your answer to two decimal places in milliseconds. Question 3 O pts Consider the following signal: v(t) = sin 21.4,998t + sin 27.5,018t. [This is a dummy question. Please answer the following question based on the details given here, including working. Enter 0 in the answer box to this question.] Question 4 2 pts You measure the signal voltage from the previous question versus time using an oscilloscope. Determine (calculate) the oscilloscope settings required to see both signals in the Fourier transform. [Hint: Consider what range and resolution of frequencies are required to detect and distinguish both signals.]
