In a balanced modulator, 2 AM-modulators are connected in a way that the resultant signal does not contain the carrier spectrum, i.e. to generate a Double Side-band suppressed carrier (DSB-SC).
Analysis:
The circuit diagram of a balanced modulator is as shown:
The resultant DSB signal is the difference of the two, i.e.
The frequency spectrum of the DSB-SC signal:
The standard DSB-SC equation is given as:
Assuming a single tone message signal as:
The DSB-SC signal can be written as:
∴ The output of balanced modulator contains the modulation frequency, LSB and USB.

Suppressed Carrier Balanced Modulation
Amplitude modulation is a technique used to transmit information by varying the strength of the carrier wave in proportion to the message signal. In suppressed carrier balanced modulation, the carrier wave is completely removed from the modulated signal. This type of modulation has several characteristics that make it useful in certain applications.
Key Points:
- Carrier Suppression: In suppressed carrier balanced modulation, the carrier wave is completely removed from the modulated signal. This means that the transmitted signal only contains the sidebands, which carry the actual information.
- Balance: The term "balanced modulation" refers to the fact that the modulation process involves the addition and subtraction of two identical modulating signals. This helps in achieving carrier suppression.
- Advantages: By suppressing the carrier, the power consumption of the transmitter is reduced since no energy is wasted on transmitting the carrier wave. Additionally, the bandwidth efficiency is improved as only the sidebands containing the information are transmitted.
- Applications: Suppressed carrier balanced modulation is commonly used in radio communication systems where bandwidth efficiency is crucial. It is also used in some types of data transmission systems where power consumption needs to be minimized.
In conclusion, suppressed carrier balanced modulation is a type of amplitude modulation where the carrier wave is completely removed from the modulated signal. This has advantages in terms of power consumption and bandwidth efficiency, making it suitable for certain communication applications.
