Phase-Modulated Carrier Systems TRIZ Cases

Phase synchronization shifts a toggle pattern against a selected clock to keep phase error within 0.1 UI and avoid high-speed MUX data errors.

A 3x-carrier digital IQ phasor approach demodulates PSK signals without analog oscillators or trig functions, improving noise tolerance.

Fixed-rate ADC sampling with digital I/Q coefficients rejects noise, captures phase components, and removes analog demodulation hardware.

Fixed-rate ADC sampling with digital I/Q coefficients rejects noise, measures phase, and removes analog multipliers and filters.

A PLL-synchronized test mode calibrates gain errors for accurate signal strength estimation while isolating the correction circuit to cut interference and power use.

A two-filter I/Q correction chain uses cross-path filtering and matched delays to cut side-band leakage in zero-IF and low-IF TX/RX.

A super-regenerative amplifier turns BPSK phase changes into amplitude signals, cutting receiver complexity and power without local oscillators.

Cascaded digital delay cells in an artificial transmission line enable near-instant phase shifts with low PVT sensitivity and sub-20 ps settling.

Separating right- and left-hand circular signals enables accurate polarization plane detection without complex high-frequency switching noise.

Switched DACs and an analog combiner generate quadrature RF signals with higher power efficiency and lower heat dissipation.
