Explain, in your own words, what is double sideband” and “suppressed carrier” mean regarding the output waveform of this modulation technique? Compare this to the output waveform for AM.

In Double sideband and suppressed carrier (DSB-SC, or simply DSB) modulation, a modulated signal is,

Multiplication by the sinusoid gives the two shifted as well as the scaled replicas of the original signal spectrum:

DSB modulation is the modulations which modulate the output signal include two side band of frequencies. Content of the signal is located under the carrier frequency which is known as band frequency as well as the signal content situated above the carrier frequency is known as Upper side band frequency.

The DSB signal modulation is similar to AM expecting the demodulator. In AM the wrapping detector is used as the demodulator where the detector of the synchronous is used as demodulator during DSB modulation.

The final modulated signal of DSB is below,

AM output Wave:

1). what is the maximum peak-to peak voltage that should be applied to the Multiplier module to follow safe usage procedure?

Measure the amplitudes of A and B of a massages as well as carrier signals at the inputs of the Multiplier modulator for the safe usages procedures,

The output of the DSB-SC is given by,

Peak to peak voltage of eth display is       

                                                                                Peak-to-peak = 2kABVolts

Whereas, “k” is the scaling factor which is the property of the Multiplier modulator which calculates the magnitudes of the parameters, now find the magnitude of Multiplier for the scale factor k, is given below

k, is the dimensional less quantity.

2). what range of frequencies can be generated using the audio oscillator? Does this range make sense when compared to the range of human hearing?

By using the audio oscillator the range of the frequencies is approximately 16Hz to 20kHz.And the range of the human hearing is 20Hz to 20 kHz, which are more sensitive sounds among 1 kHz along 4 kHz. No, the range of the audio oscillator frequencies does not make any sense, because its frequency start form 16Hz to 20 kHz, where the lowest frequency of human can hear is 20Hz which is greater than the audio oscillator frequency.
