Digital Signals is nothing but discrete in time and quantized in Amplitude
Advantage of DSP
Ø Greater Accuracy
Ø We store digital Information easily
Ø Less time process
Ø More flexiable
Disadvantage of DSP
Ø Complex to design
Ø More power consuming
Ø Choosing of Band limited
Ø Band limited
Application of DSP
Ø Communication
Ø Bio Medical Application
Ø Instrumentation and control
Ø Military
Ø Image processing
Basic Block of DSP
Classification of DT Signal
1. Deteriminstic Signals (or) Random Signals
2. Even (or) ODD Signals (cos/sin)
3. Periodic (or) Apelindic Signals
4. Energy (or) Power Signals
DT Systems :-
1. Static (or) Dynamic (memoryless/memory)
2. Causal (or) Non-Causal
3. Stable (or) unstable (BIBO/not BIBO)
4. Time Varient (TV) (or) Time Invarient (TIV)
5. Linear (or) non-Linear (superposition theorem/not satisfying superposition Theorem)
