What is DSP and its applications?

DSP is used primarily in arenas of audio signal, speech processing, RADAR, seismology, audio, SONAR, voice recognition, and some financial signals. For example, Digital Signal Processing is used for speech compression for mobile phones, as well as speech transmission for mobile phones.

How is DSP used in seismology?

Seismic signal processing, as a subfield of digital signal processing (DSP), focuses on the processing of seismic data to suppress noise, enhance signals and migrate seismic events to the appropriate location in the subsurface.

What is the most basic value obtained from geophysical signal processing?

Importance of Geophysical Signal Processing We have already mentioned the most basic value of this effort, which is to provide us with a picture of the interior of the earth we would otherwise not have access to. These processed images are widely used for commercial purposes in oil, gas, and mineral exploration.

What is the main focus of Geophysics?

Geophysics is the study of the physics of the Earth and its environment in space. One emphasis is the exploration of the Earth’s interior using physical properties measured at or above the Earth’s surface, together with mathematical models to predict those properties.

What are the applications of FIR filter?

FIR Filters are used due to their stability and linear phase properties. Digital filters in DSP Application as follows: 1) Military- Radar signal processing, sonar signal processing, navigation, secure communications and missile guidance.

What is seismic signal?

Seismic signals are usually transient waveforms radiated from a localized natural or man- made seismic source. They can be used to locate the source, to analyze source processes, and to study the structure of the medium of propagation.

How is seismic data processed?

There are three primary steps in processing seismic data — deconvolution, stacking, and migration, in their usual order of application. Figure 1.5-1 represents the seismic data volume in processing coordinates — midpoint, offset, and time. Deconvolution acts along the time axis.

What is magnetic survey geophysics?

Magnetic surveys are a geophysical method to image anomalies in the earth’s magnetic field caused by source bodies within the sub-surface. Magnetics are commonly used with gravity as a low cost way to understand the structure of the subsurface during the beginning phases of exploration.

Who is called geophysicist?

Geophysics applies the principles of physics to the study of the Earth. It deals with such things as the movement of the Earth’s crust and the temperatures of its interior. Another subject is the behavior of the still-mysterious geomagnetic field.

What is the limitation of DSP application?

DSP requires an anti-aliasing filter before ADC and re-construction filter after DAC so it requires ADC and DAC modules. DSP dissipates higher power compared to ASP because DSP processed signals at high speed and moreover it consists of higher internal hardware resources.
