Solved: Derive the expression for heart rate in beats per minute given the values of R
Chapter 7, Problem 7.104(choose chapter or problem)
Derive the expression for heart rate in beats per minute given the values of R and C and assuming that the capacitor discharges when its voltage reaches 75% of the source voltage \(V_{s}\). The expression, given in the Practical Perspective, is repeated here for convenience:
\(H=\frac{60}{-R C \ln 0.25} \quad \text { [beats per minute]. }\)
