Which is are the applications of DSP?

DSP is used primarily in areas of the 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.

What are the applications of DSP write any two applications?

DSP applications include audio and speech processing, sonar, radar and other sensor array processing, spectral density estimation, statistical signal processing, digital image processing, data compression, video coding, audio coding, image compression, signal processing for telecommunications, control systems.

How is DSP used in ECG?

The signal from the ECG preamplifier is acquired through the Codec input of the DSP starter kit. The acquired data is subjected to signal processing techniques such as removal of power line frequencies and high frequency component removal using wavelet-denoising technique.

What are the advantages of DSP?

Advantages of digital signal processing DSP offers high accuracy. Hence, filters designed in DSP have tighter control over the output accuracy. Comparatively cheaper than an analog counterpart. Reconfiguration is very easy and only code or DSP program needs to be flashed after changes as per requirement.

What is an electrocardiogram and how is it performed?

An electrocardiogram (ECG or EKG) records the electrical signal from the heart to check for different heart conditions. Electrodes are placed on the chest to record the heart’s electrical signals, which cause the heart to beat. The signals are shown as waves on an attached computer monitor or printer.

What is ECG signal?

The electrocardiogram (ECG) signal reflects the electrical activity of the heart observed from the strategic points of the human body and represented by quasi-periodic voltage signal.

What is the limitation of DSP application?

Following are the disadvantages of DSP: ‚ě®The use of DSP requires anti-aliasing filter before ADC and re-construction filter after DAC. Moreover it requires ADC and DAC modules. Due to use of this extra components complex of DSP based hardware increases.

What ECG can detect?

An electrocardiogram (ECG) is a medical test that detects cardiac (heart) abnormalities by measuring the electrical activity generated by the heart as it contracts. The machine that records the patient’s ECG is called an electrocardiograph.

What is aVF in ECG?

aVF means augmented Vector Foot; the positive electrode is on the foot. NOTE: although the F stands for foot, please conceptualize the positive electrode of aVF as being at the umbilicus. Now combine the three limb leads I, II, III. And the three augmented Vector leads aVR, aVL, aVF.

What services do we offer for digital signal processing in radar?

Our services for Digital signal processing in radar system are complimented by our radar & signal processing applications which include: DSP Algorithm implementation, DO178 Complaint Application Development and Linux / Vxworks based client application development services.

What is the main task of a radar signal processor?

The main task of a radar’s signal processor isto make decisions. After a signal has been transmitted, the receiver starts receiving return signals, with those originating from near objects arriving first because time of arrival translates into target range.

What are the different types of radar?

There are many forms of RADAR – such as continuous, CW, Doppler, ground penetrating or synthetic aperture; and they’re used in many applications, from air traffic control to weather prediction. In the modern Radar systems digital signal processing (DSP) is used extensively.

How do aircraft surveillance radars work?

Combining information: Secondary surveillance radars like those located on airports can ask an aircraft’s transponder for information like height, flight number or fuel state. Pilots may also issue a distress signal via the transponder.
