### Explanation of question 1

Fig. 17.2 represents the block diagram of a VHF., c.w. transmitter. If X represents the driver, Y the oscillator and Z the frequency multiplier stages, the correct order is

1. X, buffer amplifier, Z, Y, power amplifier
2. Y, buffer amplifier, X, Z, power amplifier
3. Y, buffer amplifier, Z, X, power amplifier
4. Z, buffer amplifier, X, Y, power amplifier

The answer is :- 3 The conventional order is: oscillator — buffer amplifier — frequency multipliers — driver — power amplifier.
