![]() ![]() ![]() An M-sequence generator having a linear feedback shift register that generates an M-sequence, also comprising: a mask table storing mask data corresponding to at least two different phase shifts of the M-sequence a masked operation circuit coupled to said mask table, performing logic operations on data read in parallel from said linear feedback shift register and mask data read from said mask table, thereby obtaining shifted state data and a control unit coupled to said mask table, selecting the mask data supplied to said masked operation circuit, loading the shifted state data from said masked operation circuit into said linear feedback shift register, and repeating these operations, selecting different mask data in said mask table, to obtain an arbitrary total phase shift in said M-sequence.ΔΆ. ![]()
