1.   Radio used for communication uses a constant frequency carrier with some kind of amplitude modulation.

2.   The sequence generator produces the phase control signals and is triggered by step command pulses from a constant frequency clock.

3.   The stepping rate is fixed by a constant frequency clock, which is controlled by a one-bit signal from the microprocessor.

4.   Could we move on to the constant frequency generator problems er how much do by this?

5.   Erm the constant frequency generator is not actually delaying the first flight, the, the first aircraft will not have a constant frequency generator on board it.

6.   We will introduce the constant frequency generator at prototype number four.

7.   According to federal agents, Moss used a police scanner to intercept the pager messages, which are sent over a constant frequency.

8.   Doppler radar is used chiefly to make precise speed measurements by transmitting a continuous wave of a constant frequency, and uses the same antenna for transmitting and receiving.

9.   Other bats use a constant frequency of sound.
