There are two methods used for SSB Transmission. This is the filter method of SSB suppression for transmission. Fig. illustrates the block diagram of this method. This carrier frequency is then fed to the balanced modulator through a buffer amplifier which isolates these two stages.

Let us now discuss the two in detail: 1. Frequency discrimination method. First, have a look at the block diagram of Filter method for suppression of one sideband. The balanced modulator employed here generates DSB-SC amplitude modulated wave as its output.

The following figure shows the block diagram of SSBSC modulator using frequency discrimination method. In this method, first we will generate DSBSC wave with the help of the product modulator. Then, apply this DSBSC wave as an input of band pass filter.

SSB-SC Generation by Filter Method is covered by the following Points: 0. Analog Communication 1. Amplitude Modulation 2. SSB-SC - Single Side Band Suppressed Carrier 3. SSB-SC...

Dec 17, 2015 · Filter Method for Generating SSB Signal. The filter method can be used for generating the SSB modulated wave if the message signal satisfies the following conditions : The message signal should not have any low frequency content .

SSB Modulation by DSBSC-AM and Filtering • In single-sideband(SSB) modulation only the upper sideband or the lower sideband is transmitted. Thus, SSB modulation requires half the bandwidth of AM or DSBSC-AM modulation. • We will assume that the baseband message signal m(t) is band limited with a cutoff frequency W which is less than the ...

shows a block diagram of an SSB transmitter using the filter method. As the name implies it is a method of generating SSB by using a very selective filter to remove the unwanted sideband.

Mar 17, 2025 · Consider the below block diagram: It has two filters and a multiplier. The first filter is the carrier filter that suppresses the carrier for efficient transmission. The second filter is the baseband filter that recovers the baseband signal. The multiplier is …

The phasing method of SSB generation is based on the addition of two DSBSC signals, so phased that their upper sidebands (say) are identical in phase and amplitude, whilst their lower sidebands are of similar amplitude but opposite phase.

A block diagram of an SSB transmitter employing this system is shown in Figure 4-4. The key circuits in this transmitter are the balanced modulator and the sideband-suppression filter. The special considerations involving Methods of Suppressing Unwanted Sidebands will …
