I’ve finished reading it.

It’s a good idea.

AES with a key size of 128 bits has 10 rounds.

AES operates in GF(2^8).

All AES rounds are identical.

AES encryption and decryption are not identical, i.e., they require (slightly) different algorithms.

They are never in phase, regardless of the frequency

The phase shift with respect to the voltage source is around 0^o

The frequency is greater than 2kHz

The phase shift with respect to the voltage source is around 90^o

The frequency is approx 1258 Hz

The phase shift with respect to the voltage source is around -58^o

The frequency is approx 1258 Hz

The phase shift with respect to the voltage source is around 180^o

The real circuit is resonant for

R3 = 5.1 ohms

R3 = 10 ohms

but not resonant if

R3 = 20 ohms

R3 = 100 ohms

The amplitude of the impedance goes to infinity.

The phase of the impedance also goes to infinity.

The amplitude of the impedance goes to infinity.

The phase of the impedance changes abruptly from 90^o to -90^o

The amplitude of the impedance is equal to 100 ohms

The phase of the impedance changes very slowly

The amplitude of the impedance is zero.

The phase of the impedance changes is also zero.
