Determine the input impedance of the circuit
Web12. Measure the input impedance r. i. To do this, use the setup shown in the circuit diagram in Figure 7-2. Use the input signal from the function generator (100mVp-p @ 4kHz). 13. Measure the value of v. in. Set up an equation relating v. x. and v. in. Use that equation to solve for the value of the AC input impedance z. i. 14. WebThe output impedance op-amp is similar to the input impedance. But it refers to how much the source’s apparent voltage changes when it needs to supply more current. For instance, you can spot the current source impedance at work when a battery that isn’t under load has a higher voltage than a battery under load.

Weboutput resistance is much more complex than determining the input resistance. The output resistance of an amplifier is the ratio of the amplifier’s open-circuit output voltage and its short-circuit output current: oc o out sc o v R i = Again, we determine these values by analyzing the small-signal amplifier circuit.

WebA capacitor or inductor have imaginary impedance (no real part, just an imaginary part. The imaginary part is called "Reactance", and L and C are called "reactive elements". Reactance is the ratio of V/I, so it has the units of Ohms, just like resistance. The impedance of an inductor is Z = jwL. WebA capacitor or inductor have imaginary impedance (no real part, just an imaginary part. The imaginary part is called "Reactance", and L and C are called "reactive elements". …
