of different media vehicles.Reach is typically expressed as a percent of the target audience:for example,if the target audience was 100.000 persons and the media schedule reached 70.000,the reach would be 70 percent.Ordinarily,costs rise at an increasing rate as higher levels of reach are sought...
Ultrasound frequency is expressed in units of Hertz (1 Hz=1 cycle per second). The range of human hearing is from about 20 Hz to 20 kHz. Others sound frequency ranges are presented on Fig. 10.3. Sign in to download full-size image Figure 10.3. Frequency ranges.Based on D. Pingret, ...
The variety of modes reviewed briefly in Section 9.3 offer the capability to vary excitation energy level (typically expressed as frequency) to capture spectroscopic data. For example, a direct amplitude and impedance analogy can be found with acoustic energy but relies upon availability of wide ...
The method is described in [3]. See Continuous-Time Transfer Function Estimation Using Continuous-Time Frequency-Domain Data (System Identification Toolbox) for more information. This algorithm typically requires less data than nonparametric approaches and is the only one that works for nonuniform f....
Natural frequency of each pole ofsys, returned as a vector sorted in ascending order of frequency values. Frequencies are expressed in units of the reciprocal of theTimeUnitproperty ofsys. Ifsysis a discrete-time model with specified sample time,wncontains the natural frequencies of the equivalent...
The magnetic field gradient is expressed in MHz per pixel. b ODMR of the \(\left|0\right\rangle \to \left|-1\right\rangle\) transition at the GSLAC. The field of view corresponds to a bandwidth between 10 MHz and 250 MHz. c ODMR of the \(\left|0\right\rangle \to \left|...
While the link between brain structure and function remains an ongoing challenge, the prevailing hypothesis is that the structure-function relationship may itself be gradually decoupling from unimodal to transmodal cortex. However, this hypothesis is con
Input and output data is sometimes expressed in the form of the Fourier transforms of time-domain input-output signals. You can encapsulate this data in a frequency-domainiddataobject. Load the data, which consists of the complex-valued input-output frequency-domain dataUandY, frequency vectorW...
This is the case for the amplifier represented in Figure 2.1. Here the lower frequency range extends all the way to 0, but in many circuits there will be a lower cutoff frequency that is greater than DC. The bandwidth is expressed as (2.5)bandwith=bw=fU−fL where fU and fL are the...
In addition, unlike many other surface spectroscopies, EELS is also capable of detecting adsorbed hydrogen, although at a lower sensitivity (typically 10−1–10−2 monolayers). It is a nondestructive technique and can be used to explore the vibrational modes of weakly adsorbed species and ...
