What is the balanced modulator?
What is the balanced modulator?
A balanced modulator mixes the audio signal and the radio frequency carrier, but suppresses the carrier, leaving only the sidebands. The output from the balanced modulator is a double sideband suppressed carrier signal and it contains all the information that the AM signal has, but without the carrier.
What is modulator explain with block diagram?
Modulation is the process of super imposition of low frequency message signal over a high frequency carrier wave. Amplitude Modulation: The block diagram is shown in fig. Explanation: The AM wave has to be fed to power amplifier to provide the necessary power.
What is a balanced modulator an example of?
Balanced Modulator [Ring Modulator] Balanced or ring modulation is a special type of amplitude modulation, where one bipolar (swinging both above and below 0 volts) signal – the modulator – is used to vary the amplitude of a second bipolar signal, known as the carrier.
What is the main function of balanced modulator?
Balanced modulator is used to suppress carrier signal to create an SSB or DSB. Explanation: Balanced modulator is used to produce 100% modulation.
What are the two types of balanced modulator?
Types of balanced modulator: The suppression of carrier can be done using the following balanced modulators: Using the diode ring modulator or lattice modulator. Using the FET balanced modulator.
Why balanced modulator is called balanced?
Balanced modulator consists of two identical AM modulators. These two modulators are arranged in a balanced configuration in order to suppress the carrier signal. Hence, it is called as Balanced modulator.
What are the methods for generating SSB SC signal?
There are three well known methods of SSB generation using analog techniques, namely the filter method, the phasing method, and Weaver’s method. This experiment will study the phasing method. You have already modelled a DSBSC signal.
Where is modulation done?
The modulation is done at the carrier signal while transmitting that signal. Hence the carrier signal properties get modulated. The receiver section demodulates the modulated signal to extract the original signal.
Why is it called a balanced modulator?
What are the applications of balanced modulator?
These devices were designed for use where the output voltage is a product of an input voltage (signal) and a switching function (carrier). Typical applications include suppressed carrier and amplitude modulation, synchronous detection, FM detection, phase detection, and chopper applications.
What are the components in a balanced modulation?
Balanced modulator consists of two identical AM modulators. These two modulators are arranged in a balanced configuration in order to suppress the carrier signal. Hence, it is called as Balanced modulator. The same carrier signal c(t)=Accos(2πfct) is applied as one of the inputs to these two AM modulators.
