de-emphasis is the complement of pre-emphasis, in the antinoise system called emphasis. Emphasis is a system process designed to decrease, (within a band of frequencies), the magnitude of some (usually higher) frequencies with respect to the magnitude of other (usually lower) frequencies in order to improve the overall signal-to-noise ratio by minimizing the adverse effects of such phenomena as attenuation differences or saturation of recording media in subsequent parts of the system.
Special time constants dictate the frequency response curve, from which one can calculate the cutoff frequency.
What else can I help you with?
What are electronic and mechanical equipment called?
Digital circuits are the most common physical representation of Boolean algebra and are the basis of all digital computers. Computer's industrial processes are constructed of digital circuits.
Can 555 timer be considered a digital device?
You can use it in both analog and digital circuits but it is considered as a digital device.
What do digital circuits mostly use?
Bipolar Transistors and Diode's .
What are the differences between analog and digital filters?
The ANALOG FILTER used in analog circuits.The DIGITAL FILTER USED IN DIGITAL circuits.
What are the advantages of using digital signals and why?
* Digital signals suffer less interferences than analogue signals. This means that when you listen to a digital signal you won't hear a hissing sound, as within digital signals regenerator circuits are used to clean "noisy" pulses. * Digital signals can be made very short so more pulses can be carried around each second, which means more information can be passed on.
Why digital communication is known as digital communication?
because it's digital communication.
What are electronic and mechanical equipment called?
Digital circuits are the most common physical representation of Boolean algebra and are the basis of all digital computers. Computer's industrial processes are constructed of digital circuits.
Is the intigrated circuit is an analog or digital device?
Both. An IC (integrated Circuit) is a compact form of several electronic circuits. These circuits may be analog or digital.
Why you need modems on digital circuits?
In digital circuits modem is used to multiplex and demultiplex the digital data.multiplexing means the digital signals amplitude or frequency or phase is varied with a carrier signal.at the receiver end the carrier signal is separated out and original digital signal is received
Can 555 timer be considered a digital device?
You can use it in both analog and digital circuits but it is considered as a digital device.
