alternating current changes direction periodically while DC direct current flows in one direction only 2 What is the function of a diode Answer A diode allows current to flow in one direction only acting as a oneway valve for electrical current 3 What is Ohms Law 3 Answer Ohms Law states that the current through a conductor is directly proportional to the voltage applied across its ends and inversely proportional to its resistance 4 What is the difference between a resistor and a capacitor Answer A resistor opposes the flow of current while a capacitor stores electrical energy in an electric field 5 What is the unit of measurement for electrical power Answer The unit of measurement for electrical power is the watt W Communication Systems 1 What is the difference between analog and digital signals Answer Analog signals are continuous and vary smoothly over time while digital signals are discrete and represent information using binary code 2 What is modulation Answer Modulation is the process of modifying a carrier wave to transmit information 3 What is the difference between AM and FM modulation Answer AM amplitude modulation varies the amplitude of the carrier wave while FM frequency modulation varies the frequency of the carrier wave 4 What is the role of an antenna in a communication system Answer An antenna converts electrical signals into electromagnetic waves for transmission or vice versa 5 What is the difference between simplex halfduplex and fullduplex communication Answer Simplex allows communication in one direction only halfduplex allows communication in both directions but not simultaneously while fullduplex allows communication in both directions simultaneously Digital Signal Processing 1 What is the purpose of a digital filter Answer A digital filter modifies the frequency content of a digital signal allowing for specific frequency components to be emphasized or attenuated 2 What is the difference between FIR and IIR filters Answer FIR finite impulse response filters have a finite impulse response while IIR infinite impulse response filters have an infinite impulse response 3 What is the NyquistShannon sampling theorem Answer The NyquistShannon sampling theorem states that a signal can be perfectly reconstructed from its samples if the sampling rate is at least twice the maximum frequency of the signal 4 What is the difference between a Discrete Fourier Transform DFT and a Fast Fourier 4 Transform FFT Answer The DFT is a mathematical transform that converts a timedomain signal to a frequencydomain representation The FFT is an efficient algorithm for computing the DFT 5 What is the role of a microcontroller in digital signal processing Answer A microcontroller is a small computer that can be programmed to perform specific tasks including digital signal processing enabling the development of embedded systems for various applications Embedded Systems 1 What is the difference between an embedded system and a generalpurpose computer Answer An embedded system is designed for a specific purpose while a generalpurpose computer is designed to perform various tasks 2 What is the role of an operating system in an embedded system Answer An operating system manages the hardware resources and software applications in an embedded system ensuring efficient and reliable operation 3 What is the difference between a realtime operating system RTOS and a general purpose operating system Answer An RTOS prioritizes timely responses and deterministic execution crucial for real time applications while a generalpurpose operating system focuses on flexibility and resource management 4 What is the role of a peripheral in an embedded system Answer Peripherals are devices connected to the microcontroller that extend its capabilities providing inputoutput functionality communication interfaces and specialized functions 5 What are the key considerations for choosing a microcontroller for an embedded system Answer Key considerations include processing power memory size peripheral availability power consumption cost and availability of development tools and support Microprocessors and VLSI Design 1 What is the difference between a microprocessor and a microcontroller Answer A microprocessor is a central processing unit CPU that executes instructions while a microcontroller is a
