Pulse Rate Multiplication With Adjustable Output Pulse Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rate multiplication methods in electronic circuits are inflexible, as they require hardware circuitry designed backwards from final waveforms, with non-adjustable pulse intervals, limiting usage flexibility and burdening circuit designers.
Innovation Solution
A method that allows adjustable numerator and denominator in rate n/m, determining time spacing between output pulse signals, by selectively outputting n pulses from m based on user-selected interval values, ensuring the interval between adjacent pulses is an integral multiple of the original signal's interval.

1Reliability
If hardware circuitry is used to select n pulse signals out of m pulse signals, then rate multiplication can be achieved, but circuit design burden increases substantially
Solution Approach 1:
The patent replaces complex hardware circuitry with a software-based method implemented on a processor. Instead of using dedicated hardware logic to select and generate pulse signals, the invention uses a processor to execute instructions that perform the same rate multiplication function through software algorithms, significantly reducing circuit design complexity while maintaining functional accuracy
Solution Approach 2:
The patent uses a lookup table stored in memory that contains pre-calculated timing information for rate multiplication. This lookup table serves as a stored reference that the processor can quickly access and copy during operation, eliminating the need for complex real-time calculations or hardware logic while ensuring consistent and accurate pulse generation
2Ease of manufacture
If fixed pulse intervals are used in rate multiplication, then hardware implementation is simplified, but usage flexibility is reduced
Solution Approach 1:
The patent implements dynamic pulse interval adjustment by allowing the processor to modify the timing parameters based on different operating conditions. The system can adaptively change the interval between output pulses by adjusting the counter values and timing parameters in the software, providing flexibility for different applications while maintaining a relatively simple hardware structure
Solution Approach 2:
The patent enables flexible rate multiplication by allowing dynamic changes to key parameters such as the numerator and denominator values, counter thresholds, and time intervals. These parameters can be modified through software without changing the hardware configuration, enabling the same circuit to adapt to different pulse generation requirements

AI summary
The present invention discloses a rate multiplication method for counting a sequence of original pulse signals and outputting a target pulse signal. In this method a comparison data and original pulse signal sequence is received. The original pulse signal sequence is counted in order to obtain a pulse count. Comparing the pulse count and the comparison data. If the pulse count is equal to the comparison data, a corresponding original pulse signal is outputted as the target pulse signal. Reset and recount the pulse count, and obtain which repeatedly. In this present invention the pulse count and the pulse interval between the target pulse signals can be determined freely according to a rate.
