Fourier basics
As it known from Fourier series, any signal can be represented as a sum of different simple signals, which basically allow as to simplify a computation and makes possible FFT transformation.

uC: PIC16F628a
Compiler: Hi-TECH PICC
Goal: To make pulses with frequency 5Hz
Timer TMR0 module frequently used in many applications, it has next useful options:
- 8 bits counter/timer
- Internal/external oscillator for pulses counting
- An interrupt is generated after overflow
In that experiment we will make it without using interruptions.
