Abstract
Abstract A method for transmitting two digital signals includes utilizing an encoder to generate a pulse of a fixed width in a coded signal each time a positive going 0-1 transmission is detected in the pulse channel. The polarity of the pulse generated by the encoder is defined by a signal present at the signal channel input. The two digital signals are separated after transmission by a decoder which utilizes the time between two successive level changes. A signal edge in the coded signal initiates a time measurement by the decoder and when a further signal edge appears within a fixed time limit then a signal is allocated to the pulse channel. When, instead, no further signal edge appears within this time limit, the signal is allocated to the signal channel of the decoder.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
A method for transmitting two digital signals that are independent of one another via a common channel, comprising the steps of: transmitting a first and second signal including: supplying said first signal to a pulse channel of an encoder; supplying said second signal to a signal channel of the encoder; generating a pulse of fixed width in a coded signal at an output of the encoder for transmission upon every level transition of said first signal; defining a polarity of said pulse in said coded signal for transmission by said second signal; receiving said first and second signals including: separating said coded signal into said first and second signals by using time measurements between two successive level changes in said coded signal; starting a time measurement at one signal edge of said coded signal; allocating said coded signal to a pulse channel of a decoder when a further signal edge appears in said coded signal within a fixed time limit; and allocating said coded signal to a signal channel of the decoder when no further signal edge appears in said coded signal within said fixed time limit.
Claim 2
Independent Claim
187 words
A method for transmitting two digital signals that are independent of one another via a common channel, comprising the steps of: transmitting a first and second signal including: supplying said first signal to a pulse channel of an encoder; supplying said second signal to a signal channel of the encoder; generating a pulse of fixed width in a coded signal at an output of the encoder for transmission upon every level transition of said first signal; defining a polarity of said pulse in said coded signal for transmission by said second signal; receiving said first and second signals including: separating said coded signal into said first and second signals by using time measurements between two successive level changes in said coded signal; starting a time measurement at one signal edge of said coded signal; allocating said coded signal to a pulse channel of a decoder when a further signal edge appears in said coded signal within a fixed time limit; and allocating said coded signal to a signal channel of the decoder when no further signal edge appears in said coded signal within said fixed time limit.
Claim 3
Dependent Claim
20 words
A method as claimed in claim 1, further comprising the step of: transmitting said coded signal via a light waveguide.
Claim 4
Dependent Claim
26 words
A method as claimed in claim 1, further comprising the steps of: transmitting said coded signal from one sub-component to another sub-component of an x-ray generator.
