Differences: Interlaced vs Non-Interlaced Scan

Interlaced: The lines of the image are displayed on the screen by interleaving pairs on one side and odd on the other side.

Non-Interlaced: The lines are all displayed in order.

Differences Between Lines, Field, and Image

The image is divided into horizontal lines; each of these horizontal lines consists of points.

Why a Field Has 312.5 TV Lines

This is explained for several reasons. The first is that each field appears in the middle of the first line and

Sound Basics

Sound: the sensation produced in the ear by sound waves. The human ear distinguishes 3 qualities: loudness, pitch, and timbre.

Audio Sources

Audio sources generate sound signals. These include analog tuners (AM, FM) and digital tuners (DAB).

Source Features

  • Distortion: Harmonic distortion (THD) is the most important. It is measured in percentage (%). The lower the value, the better the sound quality.
  • Signal-to-Noise Ratio: Measured in dB. The higher this value, the less noise is introduced

Wireless Communication Techniques

1️⃣ Orthogonal Frequency Division Multiplexing (OFDM)

Definition:
OFDM is a multi-carrier modulation (MCM) technique where the total bandwidth is divided into multiple orthogonal subcarriers to reduce Inter-Symbol Interference (ISI) and enhance data transmission efficiency.

Block Diagram:

Transmitter:

Input Data → Serial-to-Parallel → Modulation (QAM/PSK) → IFFT → Cyclic Prefix Addition → Parallel-to-Serial → Transmission

Receiver:

Received Signal → Serial-

Understanding Telephone Networks: Technologies and Components

Posted by on Apr 4, 2025 in Electronics | 0 comments

Currently, basic telephone lines are analog, but once the signal reaches the operator, it is digitized and transmitted between different operators in the network core, making it digital. It only changes back to analog when the signal is sent to the receiver.

Today’s RTB (basic telephony network) consists of switching centers and links that unite subscribers. The Integrated Services Digital Network (ISDN) began as an attempt to develop a digital line connecting with power users. The subscriber loop
