Lab 14: High Pass RC and RLC Network
In labs ?? and ?? you built low pass RC and RLC networks. In this lab you
will build high pass networks using the same circuit components. Before coming
to lab determine how to reconfigure the components used in the earlier labs
so that they will exhibit high pass characteristics.
Measure the gain (magnitude and phase) from vin to vout
of the RC high pass circuit you have designed. Take extra points in
regions where the magnitude or phase change quickly. Compare your measured
results with values calculated for your circuit.
Does the cutoff frequency of this high pass filter (defined as the point
where vout/vin equals 0.707 ) agree with your calculations?
Build your high pass RLC network. Carefully measure and plot the gain and
phase as in Part 2 (from about 0.01w0 to about
100 w0). How do you know when you are at the resonant
frequency? Does the resonant frequency agree with the calculated value for
your circuit elements? Does the gain at resonance agree with your calculations?
