What is pulse shaping in digital communication?
What is pulse shaping in digital communication?
In electronics and telecommunications, pulse shaping is the process of changing the waveform of transmitted pulses. Its purpose is to make the transmitted signal better suited to its purpose or the communication channel, typically by limiting the effective bandwidth of the transmission.
What is pulse shaping technique used?
Explanation: pulse shaping techniques reduces the intersymbol interference. they are also used to reduce the spectral width of the modulated digital signal.
Which filter is used for pulse shaping?
The Gaussian filter is a pulse shaping technique that is typically used for frequency shift keying (FSK) and minimum shift keying (MSK) modulation. This filter is unlike the raised cosine and root raised cosine filters because it does not implement zero crossing points.
What is Nyquist pulse shaping?
Pulse shaping is one technique used in communication to overcome the degradation of signals due to ISI. Pulse shaping involves the process of choosing the time-domain and spectral shape of the symbols so that the pulses do not spread or overlap.
What is a pulse shaping amplifier?
Pulse Shaping Amplifier (PSA) is an essential component in nuclear spectroscopy system. This network has two functions; to shape the output pulse and performs noise filtering. In this paper, we describe procedure for design and development of a pulse shaping amplifier which can be used for nuclear spectroscopy system.
What is the relation between pulse shaping and matched filter?
If the pulse-shaped signal received with additive white Gaussian noise (AWGN) passes through a filter matched to the pulse applied at the transmitter, then the signal-to-noise ratio of the filter output is maximized. Such a filter is called a matched filter.
Which criterion is used for pulse shaping to avoid ISI *?
The criterion used for pulse shaping to avoid ISI is Digital communication.
What is Nyquist rate in digital communication?
In signal processing, the Nyquist rate, named after Harry Nyquist, specifies a sampling rate (in units of samples per second or hertz, Hz) equal to twice the highest frequency (bandwidth) of a given function or signal.
What is pulse shaping time?
2.1 PULSE SHAPING To assure complete charge collection from a detector, preamplifier circuits are normally adjusted to provide a long decay time for the pulse (typical decay times are on the order of 50 µs).
What is pulse processing?
Processing: Processing of pulses is of primary importance in improving their nutritive value. The processing methods used are soaking, germination decortications, cooking and fermentation. Soaking: Soaking in water is the first step in most methods of preparing pulses for consumption.
What is the technique used to reduce the effects of ISI Mcq?
Gaussian pulse shaping filter reduces the spectral occupancy and ISI. Explanation: Gaussian pulse shaping does not satisfy Nyquist criterion for ISI cancellation.
