Check the units. Capacitance is a real number with units of Farads. Impedance is a complex number whose magnitude has units of Ohms and whose phase is expressed in degrees or radians. How could they be correlated? One is frequency dependent and one is not, again how could the be correlated?If a circuit has high input impedance, does it mean that the circuit also has high input capacitance?
Is there a correlation between them?
I think the instruction page is wrong, and that would explain why it is difficult to understand.I don't understand the part "high input impedance of the receiver gives rise to high input capacitance".
