Is carrier signal present at output of double side band suppressed carrier?

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 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.
How do you connect Two DC generators together to double the output voltage?
You would connect them in series to double the output voltage.
What is an example of double counting in National Income?
cotton output and cloth output.
What is the definition of master oscillator?
An oscillator that establishes the carrier frequency of the output of an amplifier or transmitter.Source : Answers.com
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.

What is carrier amplifier?
It is a direct-current amplifier in which the dc input signal is filtered by a low-pass filter, then used to modulate a carrier so it can be amplified conventionally as an alternating-current signal; the amplified dc output is obtained by rectifying and filtering the rectified carrier signal.
