MULTI-PHASE SIGNAL GENERATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18460344 titled 'MULTI-PHASE SIGNAL GENERATION
Simplified Explanation
The patent application describes technology for generating multi-phase signals using an apparatus with multiple signal generation stages. The apparatus includes a controller that can operate in two different modes to generate different phase signals.
- The apparatus includes 2^n phase signal generation stages.
- In the first mode, the controller provides an active periodic binary signal as the mode input to each stage, along with another periodic binary signal to the remaining inputs of each stage. This combination of signals allows the stages to collectively generate a 2^n phase signal.
- In the second mode, the controller provides a first steady state signal as the mode input to 2^(n-1) odd stages, and a second steady state signal to 2^(n-1) even stages. The remaining inputs of each stage receive the same periodic binary signal as in the first mode. This configuration causes either the odd stages or the even stages to collectively generate a 2^(n-1) phase signal.
Potential applications of this technology:
- Signal processing systems that require precise synchronization of multiple signals.
- Communication systems that need to generate multiple phase-shifted signals for modulation or demodulation.
- Radar systems that require phased array antennas for beamforming.
Problems solved by this technology:
- Simplifies the generation of multi-phase signals by using a controller and multiple signal generation stages.
- Provides flexibility to generate different phase signals by switching between two modes of operation.
Benefits of this technology:
- Enables the generation of multi-phase signals with high precision and accuracy.
- Reduces the complexity and cost of signal generation systems.
- Allows for easy adaptation to different phase requirements by switching between modes.
Original Abstract Submitted
The disclosure relates to technology for generating multi-phase signals. An apparatus includes 2{circumflex over ( )}n phase signal generation stages. The apparatus also includes a controller configured to provide a mode input of each of the 2{circumflex over ( )}n stages with an active periodic binary signal with remaining inputs of each of the 2{circumflex over ( )}n stages provided with another periodic binary signal to collectively generate a 2{circumflex over ( )}n phase signal in a first mode. The controller is further configured to provide the mode input of each of 2{circumflex over ( )}(n−1) odd stages with a first steady state signal and the mode input of each of 2{circumflex over ( )}(n−1) even stages with a second steady state signal with remaining inputs of each of the 2{circumflex over ( )}n stages provided with the same periodic binary signal as in the first mode to cause either the 2{circumflex over ( )}(n−1) odd stages or the 2{circumflex over ( )}(n−1) even stages to collectively generate a 2{circumflex over ( )}(n−1) phase signal in a second mode.
