2 Impedance and Transfer Functions
... Filters are mostly used for eliminating noise, so to see them in action we need to create a noisy signal. This can be achieved by adding a high frequency signal from the function generator to a 60 Hz signal derived from the wall power lines. To start, locate the 6.3 V transformer and plug it in. Obs ...

Use the proportionality property of linear circuits to find the voltage Vx
... Find k by analysis of that circuit. We can then use k to find the output when given any input. So set Vx = 1 V and let the input be unknown. There is no current flowing through either the 22 Ω resistor or the 81 Ω resistor. This means that the voltage across each element is 0V. So we can replace the ...

Test probe
A test probe (test lead, test prod, or scope probe) is a physical device used to connect electronic test equipment to a device under test (DUT). They range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile.
