What are the kind of transmission is burst wave?

Answer 1

It is usually a set of sine waves of a specified frequency, for example 10, that start up and stop after the 10 are done. This is one burst, you can have repeating bursts.

For example, bursts at a 10% duty cycle could be a burst of 20 cycles of 1MHz, which would take 20µs, then zero volts for 180µs, then another burst, etc. The rep rate of the bursts would be 5kHz in this example
