In physics, terahertz time-domain spectroscopy ( THz-TDS) is a spectroscopic technique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitude and the phase of the terahertz radiation. Fourier transform of the above pulse.

Time domain reflectometry, specifically spread-spectrum time-domain reflectometry is used on aviation wiring for both preventive maintenance and fault location. [11] Spread spectrum time domain reflectometry has the advantage of precisely locating the fault location within thousands of miles of aviation wiring.
The ITU-T G.hn standard, which provides high-speed local area networking over existing home wiring (power lines, phone lines and coaxial cables) is based on a PHY layer that specifies OFDM with adaptive modulation and a Low-Density Parity-Check FEC code. Wireless local area networks (LAN) and metropolitan area networks (MAN)
