1. Construct the circuit as in Figure 2.1 on veroboard. Again, the circuit parameters are: 1 = 5.6 Ω, 2 = 1 Ω, 1 = 2.2 Ω, 1 = 470 Ω, 2 = 1 Ω, 2 = 4.7 Ω, 1 = 4.7 , 2 = 10 , 3 = 1 , = 28 ,
2. Measure the DC voltages using multimeter and record in Table 4.4.
3. Measure source voltage, 1 & 2 and source resistance, 1 & 2 values
4. Then, calculate 1 & 2 using the measured 1, 2,1 and 2 values

p/s: I used LTspice

As written, this makes no sense.

the circuit parameters are: 1 = 5.6 Ω, 2 = 1 Ω, 1 = 2.2 Ω, 1 = 470 Ω, 2 = 1 Ω, 2 = 4.7 Ω, 1 = 4.7 , 2 = 10 , 3 = 1 , = 28 ,
How do these values relate to the components shown in circuit diagram?
The values look far too low to be practical.

Construct the circuit as in Figure 2.1 on veroboard.
The question asks that you use a soldering iron and physically build the thing, melt some solder.

How can the circuit do anything without having a supply voltage?
Also, nothing can be calculated without the part number showing the datasheet specs for the Mosfets.

The parameters have no explanation. What is 1 and what is 2? Why are there many 1 and 2 resistances and other numbers.?

This looks like a home work, assigned by a teacher’s assistant who doesn’t have the foggiest idea about practical electronics circuits.

I think the assignment has a poor translation into English.
It has a bunch of "parameter" numbers without any descriptions.
Vdd is supposed to be a given parameter.
You cannot calculate the output without knowing the input level and frequency.
The resistor values are much too low!
The capacitor values are not known.

Instead of paraphrasing, the OP should show a clear copy of the full exercise, including the table.

Most homework posts fail there.
