The working principle and advantages/disadvantages of balanced circuits

A balanced circuit is a two-wire circuit. In a balanced circuit, the impedance to ground of each of the two wires—and of any circuit connected to them—is equal to the impedance of all other wires. A typical example of a balanced circuit is a differential amplifier.

Methods of Application and Circuit Principles of Echo Suppressors

An echo suppressor is a device used in two-way circuits to reduce the echo energy caused by signals transmitted from the other party. It is primarily employed in the telecommunications field.

What is frequency response and how is it applied?

Frequency response refers to the phenomenon where, when an audio signal with a constant voltage output is connected to a system, the sound pressure produced by the speaker increases or decreases as frequency varies, while the phase shifts in response to changing frequencies. This interrelated variation between sound pressure, phase, and frequency is what we call the frequency response. It also describes the range of frequencies that an audio system can reproduce within acceptable amplitude limits—and within this range, the degree of variation in the signal is similarly referred to as the frequency response, or frequency characteristics.

Introduction to Time Division Multiplexing Standards

Time-Division Multiplexing (TDM) uses different time slots on the same physical connection to transmit multiple signals simultaneously, effectively enabling multiplexed transmission. In TDM, time serves as the key parameter for dividing the signal, so it’s crucial that each signal occupies a distinct, non-overlapping segment on the time axis. Essentially, TDM divides the total transmission time allocated to the channel into discrete time slots, assigning each slot exclusively to one of the signal sources for use.

Simultaneously transmitting over multiple parallel channels

Parallel transmission refers to the process where data is sent in groups simultaneously over multiple parallel channels—essentially, it’s the transfer of several data bits between devices at the same time during communication.

Video Signal Metrics and Testing Methods

Video signal amplitude: The standard video signal amplitude is 1 Vp-p, consisting of two test metrics: 1) White bar amplitude (video level): 700 mV 2) Sync pulse amplitude: 300 mV

Signal compensation (pre-emphasis, de-emphasis, equalization)

Pre-emphasis is a signal-processing technique used at the transmitting end to compensate for the high-frequency components of the input signal. As signal rates increase, the signal suffers significant degradation during transmission. To ensure that the receiving end captures a cleaner signal waveform, it’s essential to restore the degraded signal—this is where pre-emphasis comes in. The core idea behind pre-emphasis is to boost the high-frequency content of the signal at the beginning of the transmission line, counteracting the excessive attenuation these high-frequency components typically experience as they travel. Importantly, pre-emphasis has no impact on noise levels, thereby effectively improving the output signal-to-noise ratio.

How video image colors are processed

A color mode is a model that represents a specific color in digital form—or, in other words, a method for recording the colors in an image. The main color modes include: RGB mode, CMYK mode, HSB mode, Lab color mode, Bitmap mode, Grayscale mode, Indexed Color mode, Duotone mode, and Multichannel mode.
