Abstract
Abstract The interleaved dipulse sequence generating apparatus decomposes the data pulses of a data transmission or recording channel into pairs of spaced apart subpulses denoted as dipulses. The dipulses are interleaved or nested with respect to each other and without interference therebetween to provide an interleaved dipulse sequence signal which is conveyed on the channel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
61 words
In a data transmission or recording channel having a source of data pulse signals, interleaved dipulse sequence generating apparatus comprising means for decomposing each said data pulse into a pair of spaced apart subpulses thereby generating a dipulse, means for interleaving said dipulses without interference therebetween to provide an interleaved dipulse sequence signal in accordance with said data pulse signals, and
Claim 2
Dependent Claim
61 words
In a data transmission or recording channel having a source of data pulse signals, interleaved dipulse sequence generating apparatus comprising means for decomposing each said data pulse into a pair of spaced apart subpulses thereby generating a dipulse, means for interleaving said dipulses without interference therebetween to provide an interleaved dipulse sequence signal in accordance with said data pulse signals, and
Claim 3
Dependent Claim
11 words
means for conveying said interleaved dipulse sequence signal on said channel.
Claim 4
Dependent Claim
11 words
means for conveying said interleaved dipulse sequence signal on said channel.
Claim 5
Dependent Claim
63 words
The apparatus of claim 1 in which said means for decomposing comprises means for decomposing each said data pulse into a pair of spaced apart subpulses, one said subpulse having a magnitude and polarity in accordance with the magnitude and polarity of said data pulse and the other said subpulse having a polarity opposite that of said one subpulse thereby generating said dipulse.
Claim 6
Dependent Claim
69 words
The apparatus of claim 1 in which said means for decomposing comprises means for decomposing each said data pulse into a pair of spaced apart subpulses, one said subpulse having a magnitude and polarity in accordance with the magnitude and polarity of said data pulse and the other said subpulse having the same magnitude as and a polarity opposite that of said one said subpulse thereby generating said dipulse.
Claim 7
Dependent Claim
115 words
The apparatus of claim 1 in which said data pulse signals occur in respective data intervals and said means for decomposing comprises means for decomposing each said data pulse into a pair of spaced apart subpulses, one said subpulse having a magnitude and polarity in accordance with the magnitude and polarity of said data pulse and the other said subpulse having a polarity opposite that of said one subpulse, one of said subpulses occurring in a first portion of the data interval corresponding to said data pulse and the other of said subpulses occurring in a second portion of the data interval following the data interval corresponding to said data pulse thereby generating said dipulse.
Claim 8
Dependent Claim
111 words
The apparatus of claim 4 in which said means for decomposing comprises means for decomposing each said data pulse into a pair of spaced apart subpulses, one said subpulse having a magnitude and polarity in accordance with the magnitude and polarity of said data pulse and the other said subpulse having the same magnitude as and a polarity opposite that of said one said subpulse, one of said subpulses occurring in a first portion of the data interval corresponding to said data pulse and the other of said subpulses occurring in a second portion of the data interval following the data interval corresponding to said data pulse thereby generating said dipulse.
Claim 9
Dependent Claim
115 words
The apparatus of claim 1 in which said data pulse signals occur in respective data intervals and said means for decomposing comprises means for decomposing each said data pulse into a pair of spaced apart subpulses, one said subpulse having a magnitude and polarity in accordance with the magnitude and polarity of said data pulse and the other said subpulse having a polarity opposite that of said one subpulse, one of said subpulses occurring in the first half of the data interval corresponding to said data pulse and the other of said subpulses occurring in the second half of the data interval following the data interval corresponding to said data pulse thereby generating said dipulse.
Claim 10
Dependent Claim
110 words
The apparatus of claim 6 in which said means for decomposing comprising means for decomposing each said data pulse into a pair of spaced apart subpulses, one said subpulse having a magnitude and polarity in accordance with the magnitude and polarity of said data pulse and the other said subpulse having the same magnitude as and a polarity opposite that of said one subpulse, one of said subpulses occurring in the first half of the data interval corresponding to said data pulse and the other of said subpulses occurring in the second half of the data interval following the data interval corresponding to said data pulse thereby generating said dipulse.
