5. Compare the break point frequency from your Bodeplot, expressed in radians/sec, with the inverse of the timeconstant that you measured and calculated in Part 2. Discuss yourresults. Since the method for finding the break point frequencyintroduced here is somewhat vague, you should not be surprised ifthere is some error
Info below
part 2
Corner frequency = 1/T= 1/RC = 1k*0.1u= 10k rad/s
Transfer function= sT/(1+sT)= s/(s+10k)

Yes the corner frequencies are close. For both curves 3dBfrequencies are coming around 10k rad/s
4. The slope observed in starting = -24.054-(-44.037)= 20 db/decwhich true for first order circuits
