The audio (AF) input (or inputs in case of stereophonic broadcasting) is usually a signal with 15 kHz maximum bandwidth and 0 dBm maximum level. Preemphasis time constant is 50 μs. The signal after passing buffer stages is applied to a modulator, … See more

The modulated signal is applied to a mixer (also known as frequency converter). Another input to the mixer which is usually produced in a crystal oven oscillator is known as subcarrier. The two outputs of the mixer are the sum and difference of two signals. … See more

There are two methods:
• Split sound system: There are two parallel transmitters, one for aural signal and one for visual signal. The signals are mixed and amplified before being combined at the output via a high power combiner. … See more

The output power of the transmitter is defined as the power during sync pulse (Real output power is variable depending on the content). The quantifiable power from the transmitting equipment and antenna are different from one another. The output power … See more
