What is frequency translation used for?
A frequency translation method is designed to shift low frequency signals to intermediate frequen- cies in order to utilize higher-frequency components. This solution, appropriate for applications involving 1-10MHz signals, can provide continuously variable gain and filtering at little cost in dynamic performance.
Is frequency translation same as frequency modulation?
Frequency translation: Modulation translates the signal from one region of frequency domain to another region. Practical size of antenna: Modulation translates baseband signal to higher frequency, which can be transmitted through a bandpass channel using an antenna of smaller size.
What do you understand by frequency translation how it can be done?
Frequency translation is the process of shifting a signal from one frequency to another, without loss of information in the signal.
What is frequency translation explain am?
The process of transferring a signal form one part of the frequency axis to the other is called Frequency translation. It occurs frequently in a Wireless communication system, that is, Frequency translation is used to transfer the pass band signal to base band signal.
What is the principle of frequency translation?
Frequency translation is the process of moving a signal from one part of the frequency axis, to another part of the axis. Frequency translation is often done in wireless communications systems to move a pass band signal to base band before demodulation.
Why frequency translation is needed?
What is the frequency translation?
What is a frequency translator?
A frequency translator is used to convert the frequency of the input signal to the frequency required for the output signal. These devices typically consist of an oscillator or PLL, and a frequency mixer.
What is frequency translation?
frequency translation: The transfer of signals occupying a specified frequency band, such as a channel or group of channels, from one portion of the frequency spectrum to another, in such a way that the arithmetic frequency difference of signals within the band is unaltered. (
What does it mean to do frequency translation?
Frequency translation is the process of moving a signal from one part of the frequency axis, to another part of the axis. Frequency translation is often done in wireless communications systems to move a pass band signal to base band before demodulation.
Do you need a rack for a frequency translator?
NEW Space Saving, patented, 1/3 rack mount Frequency Translators These unique, full function space saving, patented, translators offer the same performance and options as our full rack units but require 1/3 the rack space of a traditional unit. Space savings 1/3 rack units are only available from L3 Narda-MITEQ.
When to use compound multipliers in frequency translation?
This is frequently done within the wireless communications system to transmit a passband signal toward baseband previous to demodulation. Compound multipliers are used for performing frequency conversion; however, a more efficient technique is to employ decimation.
How is a frequency translator used in PLL?
Frequency Translation using PLL The frequency shifting of an oscillator using a small factor is known as a frequency translator. The block diagram of the frequency translator using PLL is shown below.
