Microwave Communication As the electron beam moves through a klystron’s intercavity drift space Phase modulation at the input cavity creates velocity modulation at the output cavity. Density modulation at the input cavity creates velocity modulation at the output cavity Velocity modulation at the input cavity creates density modulation at the output cavity Frequency modulation at the input cavity creates velocity modulation at the output cavity Phase modulation at the input cavity creates velocity modulation at the output cavity. Density modulation at the input cavity creates velocity modulation at the output cavity Velocity modulation at the input cavity creates density modulation at the output cavity Frequency modulation at the input cavity creates velocity modulation at the output cavity ANSWER DOWNLOAD EXAMIANS APP
