 **Chapter 1: Introduction to Digital Communication** - **Digital vs. Analog Communication**: Digital systems are less prone to noise, offer better security, and support easier multiplexing and error correction. - **Elements of Digital Communication System**: Includes Source, Encoder, Modulator, Channel, Demodulator, Decoder, and Destination. - **Sampling Theorem**: States that a signal can be completely represented by samples taken at twice its highest frequency (Nyquist rate). - **Quantization & Quantization Error**: Quantization maps analog values to a finite set of levels, introducing quantization noise. - **Pulse Code Modulation (PCM)**: A method to digitally represent sampled analog signals. Steps include sampling, quantization, and encoding. - **Differential PCM (DPCM)**: Encodes the difference between successive samples to reduce redundancy. - **Delta Modulation (DM)**: Simplified form of DPCM where only the change (increase/decrease) is transmitted. - **Adaptive Delta ...

  Equations in Computer Engineering Computer engineering involves both hardware and software, requiring a strong foundation in mathematics and equations to optimize performance, reliability, and efficiency. Below are key categories of equations relevant to the field: 1. Digital Logic & Boolean Algebra Used for designing circuits and logic gates. Basic Boolean Operations: AND: A ⋅ B A \cdot B A ⋅ B OR: A + B A + B A + B NOT: A ‾ \overline{A} A XOR: A ⊕ B A \oplus B A ⊕ B De Morgan’s Theorems: A ⋅ B ‾ = A ‾ + B ‾ \overline{A \cdot B} = \overline{A} + \overline{B} A ⋅ B = A + B A + B ‾ = A ‾ ⋅ B ‾ \overline{A + B} = \overline{A} \cdot \overline{B} A + B ​ = A ⋅ B 2. Microprocessor & Performance Analysis Used for evaluating computing efficiency. CPU Performance Equation: CPU Time = Instructions Count × Cycles per Instruction (CPI) Clock Rate \text{CPU Time} = \frac{\text{Instructions Count} \times \text{Cycles per Instru...
