Line Frequency, ROM.
With i = 0, 1, 2, 3, …, M-1.
The maximum line frequency Hz is stored in the
first memory location having address 0 and the minimum
Df −0 Hz is stored in the last t memory
location having the address M-1.
The value of the line frequencies to be stored in the
M locations of the ROM are given by
In this paper, a new simple method for accurate
measurement of line frequencies proposed. The method is
based n storing the line frequencies to be measured in
read-only memory ROM.
