Example: "The artist's work is often assumed to echo the themes of isolation and despair found in modern literature."
Alternatives: "thought to reflect" or "believed to resonate".
The target echo signal is assumed to exist in the ith pulse, then the echo signal series is yleft[nright]=left{begin{array}{l}{s}_t+cleft[nright],n=i cleft[nright],kern1.62em nne iend{array}right.
The acoustic echo paths between the loudspeakers and the microphone are assumed to be time-invariant, such that the echo contribution from the r th loudspeaker at discrete time index n is given by d_{r}(n) = sumlimits_{v=0}^{V_{r}-1} h_{r} v) cdot x_{r} n-v), (1).
(1) The echo signal is assumed to be the far-field narrowband signal.
But, an estimate of the variance of the echo signal was assumed to be known a priori, which inherently requires the AEC before the NR module.
Therein, the topmost branch contains the actual echo path, which is assumed to have Hammerstein structure.
The second term of this expression models the contribution of echoes and reverberation, which are assumed to come from all possible directions on average over all absolute positions: σ rev 2 is the power of echoes and reverberation and Ω(f) is the covariance matrix of a diffuse sound field.
However, in other studies [ 14, 15, 27] using a similar method an increased echo intensity of the vastus lateralis muscle was assumed to reflect an increased relative proportion of non-contractile tissue.
We still hear the echoes in the way news is reported; timing is assumed to be critical, as it really would be if we were active agents.
The most significant findings from the ice survey were a positive reading from the metal detector, coupled with a significant echo from the Ground Penetrating Radar, both from the small area where the frame is assumed to have sunk.
The Afghan defense official echoed that concern, saying that there was little vetting of Pashtun recruits, some of whom, he said, were assumed to be loyal to the Taliban or to the Pakistani intelligence services.
