...I. Introduction
A. Definition of the Filter
The raised cosine filter is a finite impulse response filter (FIR) which is commonly used for pulse shaping in digital modulation minimize interference . The interference is controlled in a manner that it exists only at some samples other than the samples of the original signal. Its name stems from the fact that the non-zero portion of the frequency spectrum of its simplest form is a cosine function, raised - up to sit above the frequency axis.
B. Brief Background of the Filter
Data, in communication systems, are transmitted in binary form – a combination of ones and zeroes. Most implementations of a binary system is with the use of switches. When the switch is turned on, it means logic ‘1’ and off for logic ‘0’. These ones and zeroes may represent a rectangular pulse. In the frequency domain of this rectangular pulse, an infinite duration sinc pulse can be manifested.
Figure 1. A Rectangular Pulse Train Figure 2. A Sinc Function
Taking a single rectangular pulse from the pulse train in Figure 1, it can be noted that the energy is concentrated within the limit of half the time interval. This event implies to sum the halves so that it may equal to one pulse duration, which in concept, may require twice the bandwidth for a reliable transmission. Hence, a limitation is imposed upon when considering a bandwidth limited system, if the...

Multirate Digital Signal Processing
Abstract
In traditional digital signal processing system, there is always only one simple sampling rate (that is, the sampling frequency). The output signal has the same sampling rate with the input. In modern digital systems, however, there is an
increasing need to process data at more than one sampling rate. Sometimes the output of the system is required to have a different sampling rate of the input signal. This has lead the development of multirate digital signal processing, which is a new sub-area in DSP. For example, the sampling rate for an audio CD (compact disc) is 44.1 kHz. If we want to transfer data from the CD to a DAT (digital audio tape) at a sampling rate of 48 kHz, we need to increase the frequency of the data first using a multirate approach. There are two primary options we have in multirate processing. The first is decimation. The sampling rate fs of a given signal x[n] is decreased. This approach is also called down sampling. The second is interpolation. We can increase the sampling rate fs of the given signal x[n]. This approach is also...

Digital signal processing
Digital signal processing (DSP) is the mathematical manipulation of an information signal to modify or improve it
in some way. It is characterized by the representation of discrete time, discrete frequency, or other discrete domain
signals by a sequence of numbers or symbols and the processing of these signals.
The goal of DSP is usually to measure, filter and/or compress continuous real-world analog signals. The first step is
usually to convert the signal from an analog to a digital form, by sampling and then digitizing it using an
analog-to-digital converter (ADC), which turns the analog signal into a stream of numbers. However, often, the
required output signal is another analog output signal, which requires a digital-to-analog converter (DAC). Even if
this process is more complex than analog processing and has a discrete value range, the application of computational
power to digital signal processing allows for many advantages over analog processing in many applications, such as
error detection and correction in transmission as well as data compression.
Digital signal processing and analog signal processing are subfields of signal processing. DSP applications include:
audio and speech signal processing, sonar and radar signal processing, sensor array processing, spectral...

...Analog to Digital
When the conversion takes place between analog and digital it becomes the base of all communication technologies. Just about all hardware uses digital so it is very important to convert analog signals into digital to perform support for hardware applications. All hardware devices are aimed to be digital. Therefore, devices in the future will not need conversion because they will already bedigital. There are many examples of analog to digital like a scan picture. The analog information provided by the light present in the picture is converted to digital signal to complete the process. The digital conversion use the means of binary coding for data transmission and output. The digital signals work only by using only two numbers known as one and zero (Analog to Digital). When users convert the signal to digital it allows plenty of data to be stored on a single device. This help save bandwidths and space. There are seven ways that signals are structured; direct conversion, ramp compare, successive approximation, delta encoded, pipeline, time stretch, and sigma delta. When the hardware uses one of those signals the destination hardware will find the best data encryption and utilization. The most common analog to digital conversion are the digital TVs, cameras,...
