RTOS: Real-Time Operating Systems Explained
What are Real-Time Operating Systems (RTOS)?
📌 1. What are the structure and characteristics of Real-Time Operating Systems (RTOS)?
A Real-Time Operating System (RTOS) is an OS designed to process tasks within a specific time constraint, ensuring predictable and deterministic execution. The structure of an RTOS consists of a scheduler, task management, inter-task communication, memory management, and interrupt handling mechanisms. Characteristics of RTOS include determinism, fast task switching,

Encoding Bits as Voltages
There are two primary ways bits are encoded as voltages, each with distinct characteristics:
- Non-Return to Zero (NRZ) Coding: In NRZ, a ‘0’ bit is represented by one voltage level, while a ‘1’ bit is represented by a different voltage level. The voltage remains constant during the entire bit time.
- Manchester Encoding: Manchester encoding uses transitions in voltage to represent bits. For example, a ‘0’ is
Antenna Theory: Key Parameters, Types, and Applications
Antenna Fundamentals
Emitting vs. Receiving Antennas
There is no significant difference in principle between an emitting and a receiving antenna, as the transformation is reversible. However, emitting antennas often use thicker materials to dissipate the applied power. Receiving antennas undergo strict quality control.
Key Antenna Parameters
- Resonance Frequency: The frequency at which reactive components are canceled out, leaving only resistive components.
- Bandwidth: The frequency range considered valid,
Understanding Music File Formats and Audio Concepts
Understanding Music File Formats
Music Formats:
- WAV files: An uncompressed audio format.
- CDA files: The format of commercial CDs, often larger in size.
- MP3 files: Compressed files with acceptable quality.
- AAC files: Uses a compression system reducing the size by approximately 30% while maintaining acceptable quality.
- WMA files: Developed by Windows for use with Media Player; smaller than MP3s with similar quality.
- MIDI files: A standard communication protocol for connecting musical instruments.
