every time a transmit pulse is supplied, and inverting a base band signal in polarity in every transmit sequence in response to said inversion. CONSTITUTION:The output of the 3rd balanced modulator 5 is inverted by 180 deg. every time a transmit trigger is supplied, and the polarity of the ...
The multiecho rack consists of the six remaining echos in the chain. The first two are taken from the input signal making it two extra basic echoes. The third and the fourth are taken after the distortion part and will echo the distorted signal. The last two echoes are taken after the C...
The filters have been used to improve the amplitude or bandwidth or SNR of the echo signal generated by the ultrasound transducers [13]. The hardware filters with low-pass, high-pass, and band-pass functions have been used in the ultrasound front-end circuits [14]. Low- and high-pass ...
Electron spin-echo techniques have been successfully applied to the study of disordered systems mainly due to the nuclear modulation of the echo signal, the analysis of which gives information on the structural arrangement around the paramagnetic center. Most applications to date have been carried out...
The signal reflected by a radar target, or the trace produced by this signal on the screen of the cathode-ray tube in a radar receiver. Also known as radar echo; return. ghost signal (physics) A wave packet that has been reflected or otherwise returned with sufficient delay and magnitude ...
After demodulation and range compression, the signal is decomposed into the form of Bessel series in the azimuth direction. Then, the range walk is compensated in the 2-D frequency domain by Doppler keystone transform. Next, the range curvature is corrected in the range-Doppler domain by using...
An echo canceler, rather than inserting a loss in the return path, uses the transmitted speech signal to generate a replica of the echo and subtracts this signal from the echo, thus canceling it. Using echo suppressors and cancellers reduces the echo to tolerable levels on 99% of all ...
An adaptive echo canceller for two-wire, simultaneous two-way data communication at full bandwidth uses Nyquist-interval, rather than baud-interval, processing to achieve independence from timing discrepancies between near-end and far-end terminals. The entire echo signal, and not merely baud-interval...
