Units Admittance is derived by a combination of both conductance and susceptance of the material. Conductance in an AC circuit is denoted as 'G' and its units are 'mho'. Susceptance is the imaginary part of the admittance and is denoted by the symbol 'B'.

Impedance may be pure resistance or pure reactance, but usually it is a combination of resistance and reactance. The symbol Z is used for impedance, which is expressed in ohms. Impedance takes the general phasor form. Linear vs. non linear systems application note). Frequency values are lost in the Nyquist diagram therefore it is useful to indicate the frequency of some.
Figure 1-1 also shows the mathematical relationship between R, X, |Z|, and θ. In some cases, using the reciprocal of impedance is mathematically expedient. In which case 1/Z = 1/(R + jX) = Y = G + jB, where Y represents admittance, G conductance, and B sus-ceptance.

The terms “input” and “output” tells us that we wish for signal energy to flow from the output circuit to the input circuitIt could be said that electrical resistance is the opposition to steady electric current. An ideal resistance does change with frequency when connected with DC. Impedance is the measure of the nature of opposition of the AC electricity which is created due to inductance and capacitance. This opposition varies with the frequency. and that the reciprocal of impedance is admittance, \[Y = \dfrac{1}{Z} \label{3.3} \] The units are siemens for each. It is also worth noting that, due to the division, the signs reverse. For example, a capacitive susceptance has an angle of +90 degrees and if a complex admittance has a negative angle, then the associated impedance is inductive.
