#$2.$Find the peaks and troughs for the Red and IR channel using a scipy method.

Output the heart rate in beats per min$(BPM)$ for both the Red and IR channel with text label and rounded to $2$ decimal places. Remember Red and IR channel are switched in the data.

Plot the results and mark the peaks and troughs for the red channel and graph. See Plot $3$ as an example.

Calculate the Average Peak Value, the Average Trough Value, the average Ratio of Ratios, And the average SpO $2$ for the entire run. Output that to the console with text labels and rounded to $2$ decimal places.

$h=$ None # must be above absolute value of y axis

$t=$ None # vertical distance to neighboring values

$p=400$ # height above surrounding baseline, previous $500,$ might make scalable to PPG signal

$w=10,$ # width of the peak $($at half peak height$)$

INTERCEPT$\_$SPO$2=130,$#SpO$2=$ INTERCEPT$\_$SPO$2-$SLOPE$\_$SPO$2*$Ratio

SLOPE$\_$SPO$2=36$

#$3.$

Starting with the solution for HW#$2$ add an additional section of code that calculates the BPM heart rate only for beats where there is exactly $1$ peak in between the adjacent troughs. Now recalculate this new heart rate, BPM$2,$ and display it's average and standard deviation for the ~$40$ second interval $($output to console with $2$ decimal places and properly labeled$).$ do this for file number $9.$ You only need to do this for the IR channel $($remembering that IR and red are mislabeled$).$
