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 line frequency Df +0 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 if 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. )( )( 0 0 Dfif Dff f c c i ++ + = (3)
