11. Using Timer1 and CTC mode of the ATMega32, write an AVR C program that uses the
hardware waveform generator to generate a square wave on pin OC1A with a
frequency of 50 Hz if PA1 is high, otherwise generate 60Hz. Assume XTAL = 8 MHz.

these questions are associated with the PCB

1. During in the designing process, what types of layout level do you need to consider? write out the layout level name ,and explain these levels in detail. (you can draw diagram to explain those levels)

2.what is the general procedure to design a PCB? explain in each step

3. For the micro-electronic schematic,  draw 5 simple circuits diagrams (it can be current mirror, current follower etc) that can be used in any types of PCB design.

Simplify to a minimum SOP each stating the key properties used

1) f=xyz’+xyz

2) g=x’y’z’+x’y’z+x’yz+xy’z+xyz

3) f=abc’+ab’c+a’bc+abc

4) f=(a+b’+c)(a+b’+c’)(a’+b+c)(a’+b’+c)

5) g=(x’+y’+z’)(x’+y+z’)(x’+y+z)

Find the compliment of 6, 7, 8

6) F=x’yz’+xy’z’+xyz
