Electromagnetic Transmitters TRIZ Cases

Digital signal processing unit calculates propagation delay differences using fast Fourier transform peak values to compensate for inter-channel skew in coherent optical receivers.

Digital matched filtering correlates transmitted and reflected pulses to reject backscatter and improve range resolution in degraded visual environments.

Delay line interferometer removes chirp from directly modulated laser transmitters, maintaining signal integrity without slowing rise times.

An optical transmitter module applies programmable pre-emphasis to electrical signals using stored compensation values.

A single optical demodulator separates mixed carrier signals using periodic transfer functions.

A monitoring circuit uses optical coherent detection and equivalent-time sampling to measure modulated optical signals.

Time-interleaved digital-to-analog converters reduce sample rates and energy consumption while maintaining high spectral efficiency.

Electro-optical conversion system generates optical differential return-to-zero signals using Mach-Zehnder modulators driven by pre-coded electrical inputs.

A modulator controller adjusts imbalance electrode current to stabilize phase operation.

Auxiliary signal extraction monitors phase and intensity while suppressing internal reflections that cause signal loss in Mach Zehnder interferometers.

A correlation OTDR system embeds a pseudo noise signal into an amplitude modulated data stream for continuous fiber monitoring.

Positioning the optical phase conjugator away from the midpoint reduces system complexity while maintaining effective nonlinear compensation.
