balanced modulator การใช้

• The balanced modulator output can either lead or lag the carrier's phase.
• Robecca offers her assistance as player, but she is still missing her balance modulator.
• This carrier signal is applied to two stages in the transmitter : a balanced modulator and a mixer.
• To understand how a balanced modulator works it is necessary to understand amplitude modulation and how it works.
• It is possible to generate an AM signal by taking the output from the balanced modulator and reinserting the carrier.
• A balanced modulator mixes the audio signal and the radio frequency carrier, but suppresses the carrier, leaving only the sidebands.
• In the Armstrong method, the audio signal and the radio frequency carrier signal are applied to the balanced modulator to generate a double sideband suppressed carrier signal.
• The output from the balanced modulator is a double sideband suppressed carrier signal and it contains all the information that the AM signal has, but without the carrier.
