An important parameter in the calculation of seismic hazard , maximum magnitude expressed as Moment magnitude scale is also one of the more contentious. The choice of the value can greatly influence the final outcome of the results, yet this is most likely a size of earthquake that has not yet occurred in the region under study. Image Freqmag.png f mag plot left thumb 200px Frequencymagnitude plot The seismic hazard calculation involves a double integration integral over the region, combined with the expected number earthquake frequency of earthquakes, from the smallest to the largest. The integration must close at the maximum magnitude. The figure shows a typical Earthquake frequency plot for a given region. This is a typical plot for continent al interiors. The circles represent actual earthquake data. Note that the dataset is complete for small magnitudes, but becomes erratic for the larger. At about M5, there are no records, simply because the historical record is usually too short. In some cases paleoseismology can fill some of the gap, but this is rare for continental regions. The last part of the curve, perhaps the most important part, can be filled in by inference.

Before the advent of photometer s which accurately measure the brightness of astronomical objects, the apparent magnitude of an object was obtained by taking a picture of it with a camera . These images, made on Photographic film photoemulsive film or photographic plate plates , were more sensitive to the blue end of the electromagnetic spectrum visual spectrum than the human eye or modern photometers. As a result, bluer stars have a lower i.e. brighter photographic magnitude than their modern visual magnitude , because they appear brighter on the photograph than they do to modern photometers. Conversely, redder stars have a higher i.e. fainter photographic magnitude than visual magnitude, because they appear dimmer. For example, the red supergiant star KW Sagittarii has a photographic magnitude of 11.0 to 13.2 but a visual magnitude of about 8.5 to 11. It is also common for star charts to list a blue magnitude B such as with S Doradus and WZ Sagittae .

In telecommunication , the term critical frequency has the following meanings In radio radio propagation propagation by way of the ionosphere , the limiting frequency at or below which a wave component is reflected by, and above which it penetrates through, an ionospheric layer. At vertical incidence, the limiting frequency at or below which incidence, the wave component is reflected by, and above which it penetrates through, an ionospheric layer. Critical Frequency changes with time of day, atmospheric conditions and angle of fire of the radio waves by antenna. The existence of the critical frequency is the result of electron limitation, i.e., the inadequacy of the existing number of free electrons to support Reflection electrical reflection at higher frequencies. In signal processing the critical frequency it is also another name for the Nyquist frequency . References FS1037C MS188 Critical frequency is the highest magnitude of frequency above which the waves penetrates the ionosphere and below which the waves are reflected back from the ionosphere. It is denoted by fc . Its value is not fixed and it depends upon electron density of ionosphere. Category Telecommunications telecomm stub ... more details

signal of the system. The frequency response is characterized by the Amplitude magnitude of the system ... , measured in radians or degrees, versus frequency in radians sec or Hertz Hz . These response measurements can be plotted in three ways by plotting the magnitude and phase measurements on two rectangular plots as functions of frequency to obtain a Bode plot by plotting the magnitude and phase angle on a single polar plot with frequency as a parameter to obtain a Nyquist plot or by plotting magnitude ... systems with nearly uniform time delay at all frequencies, the magnitude versus frequency ...Refimprove introduction and first section date September 2011 Frequency response is the quantitative measure of the output Frequency spectrum spectrum of a system or device in response to a stimulus, and is used to characterize the dynamics of the system. It is a measure of magnitude and phase of the output as a function of frequency, in comparison to the input. In simplest terms, if a sine wave is injected into a system at a given frequency, a linear system will respond at that same frequency with a certain magnitude and a certain phase angle relative to the input. Also for a linear system, doubling ... is time invariant, then the frequency response also will not vary with time. Two applications of frequency ... may be to reproduce the input signal with no distortion. That would require a uniform flat magnitude ...
