Question 1 The noise floor, also known as additive white Gaussian noise (AWGN), is a continuous noise level that appears over a wide spectrum when viewed in the frequency domain. True False 10 points Question 2 When considering the impact of impulse noise, we find that it is more devastating to a digital communications link, than an analog one. Therefore, error control methods should be used on all digital links. True False 10 points Question 3 When two transmitters operate...

QUESTION 2 You are attempting to implement a NOR gate by using the BJT circuit shown in Figure 2. Note that the two BJTs are identical. Vec 3V • VOLT R RS w A w B OL Figure 2: NOR gate implementation There are two operational requirements that you need to achieve: The required output voltage thresholds are: Von = 2.4 and VoL = 0.4. The current load at the base cannot exceed a certain value, i.e. Is s 1(max)...

(MATLAB question) "ecg_signal.mat" converted to a .csv file yields the following data; This is only part of the whole .mat file. Please show how to analyze the whole signal from this snapshot. 1. In the lab we analyzed filtering 60 Hz power-line noise from ECG signal using a digital (signal processing) filter. Now let's try to an analog (circuit) filter approach to remove the 60 Hz line-noise. Following is an active twin-T notch filter with transfer function: 2R 2R Here...
