Analog Signal Processing Block Diagram

A block diagram consists of blocks that represent different parts of a system and signal lines that define the relationship between the blocks.

Analog signal processing block diagram. Digital signal processing the task of dsp is to process sampled signals from a d analog to digital converter and provide its output to the d a digital to analog converter to be transformed back to physical signals digital signal processing digital signal a d processing d a. Block diagram of an analog system an analog system is a collection and interconnection of several building blocks that performs some operation on an analog input signal to produce an analog output signal. Selesnick el 713 lecture notes 1. Block diagrams are widely used by engineers for controls signal processing communications and mechatronics.

2 digital vs analog signal processing 3 applications 4 basic block diagram 5 dsp history i. Analog digital signal. In source coding the encoder converts the digital signal generated at the source output into another signal in digital form. The data or information that we perceive in real world exists in analog form while the digital devices such as cellphone calculator computer can only understand a data signal in digital domain.

Inverse sinc filter compensates the sinc roll off caused by the. Tools used in analog signal processing. A system s behavior can be mathematically modeled and is represented in the time domain as h t and in the frequency domain as h s where s is a complex number in the form of s a ib or s a jb in electrical engineering terms electrical engineers use j instead of i because current is represented by the variable i. Digital signal processing in if rf data converters.

These signal processing filters are classified into various types such as electronic filters digital filters and analog filters. Analog filter is typically used in electronics and is considered as a basic building block of signal processing. Types of signals a signal is a function that contains information which can be trans mitted displayed or manipulated. Figure 2 shows the block diagram of a typical ddc.

Digital to analog converter dac types working block diagram applications. Different source coding techniques are pcm pulse code modulation dm delta modulation. Digital signal processing is the process of representing signals in a discrete mathematical sequence of numbers and analyzing modifying and extracting the information contained in the signal by carrying out algorithmic operations and processing on the signal.

Signals are mainly classified into two types i e. In this diagram three basic signal processing operations have been included.
