5) Assuming the signal has been well-isolated, design a two-stage circuit to indicate heartbeat from an EKG signal. The first stage should amplify the biosignal to a 1V range (defined from Q-R), and the second will indicate heartbeat using a comparator. Assume the detection will occur using the R-wave of the signal. Describe how the output from the second stage indicates a heartbeat. Describe a possible third stage to provide an audible output indicating the heartbeat. Show all work. (15 points)

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
