Assuming that the integral starts at β, then:
EQUATION C-5:
Likewise, as strict integration cannot be realized in the entire cycle, so:
EQUATION C-6:
Similarly, the integral value of above equation is related to β with 2π as its period, let’s
denote it as F
F
EQUATION C-7:
It can be proved that,
EQUATION C-8:
In practical applications, it is necessary to sample the continuous analog signals and
process the data obtained with discrete algorithms. The quasi-synchronous recursive
process mentioned above can be expressed as follows:
For Equation C-4, the integral interval [x
can be divided equally into n x N sections, which results in n x N + 1 sampled data,
