Method and apparatus to generate ON-OFF keying signals suitable for communications |
摘要 |
A method and apparatus to generate an OOK-type of signal for transmitting digital data without having to use conventional mixer and oscillator circuitry as the carrier source is disclosed. The method utilizes a circuit that has a transfer characteristic comprising alternating unstable and stable operating regions, which produce respectively non-oscillatory and oscillatory output. The circuit is further characterized by having an operating point that can drive the circuit into stable or unstable operation based on the digital data. The resulting output signal is an OOK-type of signal suitable for transmission.
