pypho_symbols

Creates a sequence of symbols as defined in parameter pattern.

pypho_symbols.__init__(glova, nos, pattern, p1, p1)

Parameter Type Description
glova instance Global parameters
nos integer Numbers of bits
Default value is glova.nos
If nos is smaller 0 and the pattern is "debruijn", then the return array is length of $p1^{p2}$, otherwise as defined by nos.
pattern string Defines the bitpattern
'ones' : a sequence of ones
'singlepulse' : a single one in the middle surrounded by zeros
'random' : a random sequence of ones and zeros whith the same numbers of ones and zeros
'debruijn' : De Bruijn sequence
p1, p2 integer p1 = Number of different symbols (alphabet size)
Additional parameters needed for De Bruijn: p2 = Order of the sequence
