The high-pass filters are used to measure supply and return supply line noise. These voltages are measured across 50 Ω resistors, as illustrated in Figure 5 and Figure 6.1 In a real lab, this voltage is measured using an EMI receiver. LTspice can be used to probe the noise voltages...
Power in Series and Parallel Circuits Power is a measure of the rate of work. Per the physics law of conservation of energy, the power dissipated in the circuit must equal the total power applied by the source(s). Therefore, an interesting rule for total circuit power versus individual compo...
In the measurement of some filters, it is necessary to connect a load capacitor CL in parallel with the load resistance before testing. In order to prevent the influence on the characteristic parameters of the filter in the measurement, the input capacitance of the high impedance probe must be...
You mentioned that you used the same meter to measure the current. The Current range of a digital ammeter has some low, non-zero, internal resistance, which would add to your effective load resistance. Has this been taken into account?
