This paintings makes vast use of Soviet resources to supply an entire research of Moscow's ballistic missile defence coverage, from its origins to post-Soviet advancements. It considers the Soviets' motivations for pursuing an anti-ballistic missile potential and the level in their good fortune, and divulges that ballistic missile defence coverage used to be utilized by each political management from Krushchev to Yeltsin as a way of sending signs approximately Moscow's intentions to the West.

It is important to be aware of these factors and to take them into account before attempting to assign lines in a spectrum. (i) H O M O G E N E I T Y OF THE M A G N E T I C F I E L D We have mentioned that the line width of an absorption signal is frequently determined by the homogeneity of the magnetic field. In assessing any spectrum, it is necessary to know the resolution at the time of measurement and we therefore require an index of resolution. A convenient estimate of The Experimental Method 31 resolving power is provided by the measurement of line width.

The effect of sweep rate on the appearance of signals. Sweep rates: (a) 10 Hz per sec. (b) 0-1 Hz per sec. The Boltzmann excess of nuclei in the ground state corresponds to a magnetization of the sample in the direction parallel to the applied field. At resonance, part of this magnetization appears as a rotating component of magnetization in the plane perpendicular to the applied field. It is in fact this rotating component of magnetization which induces the absorption and dispersion signals in the receiver coil.

In fact, the sum of the noise will be proportional to the square root of the number of observations. The two basic methods by which this principle can be applied to the enhancement of sensitivity will now be outlined. 53»1407,1270 The output voltage (which is normally applied to the recorder) at a series of equally spaced frequency intervals is converted to a digital equivalent and stored in a computer. In other words, if, say, a thousand equally spaced points (frequencies) along the abscissa are selected, the computer assigns a memory address to each point and stores in that address a number which is proportional to the signal strength at the corresponding frequency.
