Electromagnetic Radiation And The Electromagnetic Spectrum

Wave Model Emr

EMR is a dynamic form of energy that propagates as wave motion at a velocity of c 3 x 1010 cm sec. The parameters that characterize a wave motion are wavelength (A,), frequency (v) and velocity (c) (Fig. 2). The relationship between the above is Figure 2 Electromagnetic wave. It has two components, Electric field E and Magnetic field M, both perpendicular to the direction of propagation Figure 2 Electromagnetic wave. It has two components, Electric field E and Magnetic field M, both...

Basic Concept Of Gps Receiver And Its Components

Basic Concept Are Dgps Survey

The main components of a GPS receiver are shown in Fig. 10. These are - RF section with signal identification and signal processing - Micro-processor for receiver control, data sampling and data processing - User interface, command and display panel Figure 10 Major components of a GPS receiver Figure 10 Major components of a GPS receiver Sensitive antenna of the GPS receiver detects the electromagnetic wave signal transmitted by GPS satellites and converts the wave energy to electric current...
