Atmospheric Changes and Observationsts will be reviewed in the light of a practical design procedure. Also limitations which might be imposed on the design due to the construction of the bandpass filters are considered. These considerations lead to a step-by-step design procedure to be presented in Chapter 14.

Two-Mode Seismo-ionospheric Disturbancesds will be described. The difference between the two amplifiers lies in the methods by which automatic gain control is achieved. In one amplifier the system of reverse gain control is used, whereas in the other, forward gain control is applied.

J. M. Conlon,K. D. Buchanan,R. F. Murphy system and almost entirely determines the amplitude and phase response characteristics. The I.F. amplifier therefore largely governs the total performance. For these reasons a great deal of attention is usually given to the design of such an amplifier.

Morphologic Study of Glucagon Releasets imposed on such an amplifier are closely related to the performance of these parts. The I.F. amplifier must, for example, be able to cope with and to supply signals of such a magnitude that proper functioning of the R.F. stages and detector circuit is ensured.
