Q

what is magnetic field

A

_H, (A/m), magnetic potential between 2 points in space (attraction)

17
Q

Gauss’s law magnetism

A

divergence of the magnetic field is equal to zero meaning the magnetic field doesnt spread out and only curls

18
Q

faradays law

A

its the circling of the electric field, changing the magnetic field can cause current to flow in wires, bigger change in magnetic field=greater voltage

19
Q

amperes law

A

about changing electric field, constant current creates a magnetic field, changing electric field also creates a magnetic field

20
Q

AND gate

A

A•B

21
Q

OR gate

A

A+B

22
Q

NOT gate

A

inverse A or input

23
Q

NOR gate

A

inverse (A+B)

24
Q

EQV gate

A

inverse A •inverse B+A•B

25
Q

XOR gate

A

A•inverse B+ inverse A•B

26
Q

what is AM

A

amplitude modulation, change in amplitude=static, overall strength baried to include sound info

27
Q

what is FM

A

frequency modulation, changes in amplitude dont effect sound because its based on frequency, frequency of carrier signal varied for sound
