ISI & Equalization error performance of the communication system. There are two major ways to i.e., the basic pulse shape u(t) and/or the channel is bandlimited. More precis (2) Unwanted electrical noise or other interference further distorts the pulse waveform. Both of these mechanisms cause the pulse shape to degrade as a function To transmit at symbol rate fs needs certain bandwidth BT and BT depends on which pulse shaping used — does the channel bandwidth B enough to As you've told the main goal of pulse shaping filter is to restrict signal bandwidth in the transmitter while in receiver you should place the matched filter to 9 Jul 2019 Pulse and Digital Circuits -Linear wave shaping.ppt - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view Among different pulse shaping filters the FIR Raised Cosine Filter is widely used in digital communication to reduce ISI. In this paper, the causes for ISI, effect of ISI Nyquist's sampling theorem plays a significant role in the design of pulse- shaping filters, which enable us to restrict the bandwidth of information-bearing pulses.

By filtering the transmitted pulses this way, the intersymbol interference caused by the channel can be kept in control.

Pulse Code Modulation (PCM), also known as baseband transmission, converts the input analog signal into digital format and transmits over a digital communication channel.

Pulse Code Modulation (PCM), also known as baseband transmission, converts the input analog signal into digital format and transmits over a digital communication channel.

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. By filtering the transmitted pulses this way, the intersymbol interference caused by the channel can be kept in control.
