No, the carrier signal is not present at the output of double side band suppressed carrier. That is what suppressed carrier means. However, the receiver has enough information to regenerate the carrier if need be. The advantage of suppressed carrier mode is that more power can be deployed to the signal-carrying portion of the modulated carrier.

What feature of the multiplier modules output suggests that is basically a DSBSC signal?
The feature of the multiplier module's output that suggests it is essentially a Double Sideband Suppressed Carrier (DSBSC) signal is the absence of a carrier frequency component in the output spectrum. In DSBSC modulation, the carrier wave is suppressed, and the output consists of two sidebands that carry the modulating information. This characteristic can be identified by analyzing the frequency domain representation, where only the upper and lower sidebands are present without the carrier frequency peak.
What are the frequency components at the output of the modulator?
The frequency components at the output of a modulator typically include the carrier frequency and the sidebands generated by the modulation process. For amplitude modulation (AM), the output contains the carrier frequency along with upper and lower sidebands, which are spaced from the carrier by the modulating frequency. In frequency modulation (FM), the output consists of the carrier frequency and a series of sidebands determined by Bessel functions, reflecting the modulation index. The specific frequencies present depend on the modulation scheme and the characteristics of the input signal.
How does the demodulated output vary with carrier amplitude?
The demodulated output is directly affected by changes in carrier amplitude. As the carrier amplitude increases, the demodulated output will also increase in magnitude. Conversely, if the carrier amplitude decreases, the demodulated output will decrease as well. Maintaining a consistent carrier amplitude is crucial for accurate demodulation in communication systems.
What is a carrier wave?
A modulated carrier wave is the output of a modulator that includes the information of the signal that is applied to the carrier.When a signal typically a piece of music in the range of say 30Hz to 30KHz is applied to an AM modulator (not sure about FM or PM) with a carrier of say 3MHz the output consists of 4 packetsUpper Sideband (Carrier + Signal) 3.000003MHz to 3.03MhzLower Sideband (Carrier - Signal) .297MHz to .299997MHzCarrier 3MHzSignal 30Hz to 30KHzEither sideband in the case of Single Side Band (SSB) or Both (.297MHz to 3.03Mhz) in the case of Double Side Band (DSB) could be referred to as modulated carrier waves
What is master oscillator?
it generates the carrier frequency of the output after passing a signal.
Does demodulated output depend on carrier amplitude?
Only in an AM system. In an FM system, variations in carrier amplitude are ironed out with hard limiting before demodulation.

Why the peak value in double ended differential amplifier is double the peak value of single ended differential amplifier for the same input signal?
The peak output value in a double ended differential amplifier is double the peak output value of a single ended differential amplifier for the same input signal because there are two outputs, one being the normal output, and the other being the inverted output. Whatever the normal output does, the inverted output does, but with a reverse sign. As a result, if one output has a value of X, then then other output has a value of -X. If you compare the two outputs, then, the difference between them will be 2X, or double the value.
How is a two tone test performed?
A pair of audio tones is applied to the audio input of a transmitter, often one designedto transmit single sideband suppressed carrier, at a level intended to produce at or near100% modulation. The transmitter output can then be examined to evaluate the peakeffective power, steady state power, RF bandwidth, harmonic distortion, and intermodulationproducts at the tone frequencies and at their harmonics.
