Webb24 apr. 2024 · Seismic data contain random noise interference and are affected by irregular subsampling. Presently, most of the data reconstruction methods are carried out separately from noise suppression. Moreover, most data reconstruction methods are not ideal for noisy data. Webb14 okt. 2014 · 6. COMPONENTS OF A COMPLEX TRACE If A (t) & θ (t) be the Amplitude & time-dependent phase respectively, then the real seismic trace can be written as: f (t)= A (t).cos θ (t) So, f* (t)=A (t).sin θ (t) Thus, F (t)= A (t).e^ (jθ (t)) 7.
