Hello,
I am a college student and this is my first time using the forum.

Anyway, I need help with two engineering projects I have been assigned.
Don't worry, you won't be helping me to cheat or anything because we have
been advised to access all available resources.

The first assignment is to build a power supply.  I don't even know where
to start!!!
The power supply has to be able to run the tape deck of a walkman.  The
transformer has to step the voltage down from 120Volts to about 4.5Volts.
There's four diodes connected creating a 4-way rectifier.  Theres also a
resistor, capacitor, and zener diode connected in the circuit.

The second assignment is to build a class A amplifier with maximum
semetrical swing and 45dB of gain or more, using a 2N222A transistor and 1
meg of input impedeance or more.

I don't even know what half of these things mean.  Also, for both
projects, we need to find the values of all of the components, they are
not given.  Any help would be greatly appreciated.  Thank you for your
attention.
