This paper presents design equations which are directly applicable to the RF circuit design of such a transmitter, and shows that the simplest practical overall output circuit turns out to be a straightforward double tuned bandpass filter. Because, in the 100 kHz carrier region being considered, ...
Clean rocks – Archie’s (1942) equations: In a “clean porous rock” (for example sandstone without clay and/or other conductive solid components), the formation water is the only electrically conductive component, because matrix (quartz) and hydrocarbons or air in the pore space are ...
This breakthrough in physics is hard to overstate. The man responsible for this conceptual revolution was the Scottish physicist James Clerk Maxwell (1831-1879), who “unified” the study of electricity and magnetism in four relatively tidy equations. ...
We will show that, while the equations and associated boundary conditions at the array ends can describe the nonlinear behavior of the array through numerical solution, if the inter-oscillator phase differences remain small, the equations may be linearized. The linearized version may be solved ...
Allows the user to calculate the the maximum allowed current of a particular track or via on a PCB for a given temperature rise. Calculated in accordance with the equations in IPC-2221A Section 6.2 (formerly IPC-D-275). Note: For via current calculations, the value used for the k constan...
The German physicist, Heinrich Hertz, set All of the proven radar systems developed prior to the war were in the out to validate Maxwell’s general equations. Hertz was able to show that VHF band. These low frequency radar signals are subject to several electromagnetic waves travelled in ...
Next, an approximate lumped-circuit model and design equations to determine the optimum length of the stubs will be investigated. Finally, the effectiveness of the proposed structure will be demonstrated experimentally. All the calculated results shown in this paper are obtained by a standard finite-...
Calculated in accordance with the equations in IPC-2221A Section 6.2 (formerly IPC-D-275). Note: For via current calculations, the value used for the k constant is the worst-case value (the same for an internal track). Based on the calculator found at http://www.mbedded.ninja/online-...
阻抗匹配与史密斯(smith)圆图 基本原理(Impedance matching and the basic principle of Smith (Smith) circular graph) Impedance matching and Smith (Smith) circular graphs: Fundamentals In this paper, the Smith circular diagram is used as a design guide for RF impedance matching. A drawing example of...
