Abstract
Abstract A method for pulse distribution includes the detection of the highest bit position in a plural bit input. A pulse sending interval corresponding to the highest input bit position is determined, and pulse trains corresponding to the highest bit position and the input bits are selected. A pulse train sum is then generated by selected pulse trains during the pulse sending interval.

Claim 1
Independent Claim
70 words
A method for pulse distribution which comprises detecting the highest occupied bit position for plural multibit inputs, determining the pulse sending interval corresponding to the highest occupied bit position, selecting one or more pulse trains corresponding to the inputs as a function of the highest occupied bit position and the input bits, and obtaining a pulse train sum by sending out said selected pulse trains in the pulse sending interval.
Claim 2
Independent Claim
70 words
A method for pulse distribution which comprises detecting the highest occupied bit position for plural multibit inputs, determining the pulse sending interval corresponding to the highest occupied bit position, selecting one or more pulse trains corresponding to the inputs as a function of the highest occupied bit position and the input bits, and obtaining a pulse train sum by sending out said selected pulse trains in the pulse sending interval.
Claim 3
Dependent Claim
17 words
A method for pulse distribution according to claim 1, wherein the number of said inputs is two.
Claim 4
Dependent Claim
17 words
A method for pulse distribution according to claim 1, wherein the number of said inputs is three.
Claim 5
Dependent Claim
52 words
A method for pulse distribution according to claim 1, wherein the highest occupied bit position is determined by logically summing the inputs in each bit position and logically multiplying each of the logical sums by NOT values of logical sums of all higher bit positions to obtain the highest occupied bit position.
