The wavelength for a frequency of 25 Mhz is:
  1. 15 metres 2. 32 metres 3. 4 metres 4. 12 metres

The frequency of a current is 60 hertz. This means:
1. a potential difference of 60 volts exists 2. the current flow is 60 amperes 3. the power dissipated is 60 watts 4. the current oscillates 60 times per second

A signal is composed of a fundamental frequency of 2Khz and another signal of 4Khz. This 4Khz signal is referred to as:
1. a fundamental of the 2Khz signal 2. a harmonic of the 2Khz signal 3. the DC component of the main signal 4. a dielectric signal of the main signal

A harmonic of a signal transmitted at 3535Khz would be expected to occur at:
1. 3,573Khz 2. 7,050Khz 3. 14,025Khz 4. 21,050Khz

An equivalent of "ONE CYCLE per SECOND" is one:
1. henry 2. volt 3. hertz 4. coulomb

If the frequency of a waveform is 100 hz, the time for one cycle is:
1. 1 second 2. 0.1 second 3. 0.01 second 4. 0.0001 second

Current in an AC circuit goes through a complete cycle in 0.1 seconds. This means the AC has a frequency of:
1. 1 hz 2. 10 hz 3. 100 hz 4. 1,000 hz

One megahertz is equal to:
1. 0.001 hz 2. 100 Khz 3. 1,000 Khz 4. 10 hz

The unit "DECIBEL" is used to indicate:
1. certain radio waves 2. single sideband signal 3. oscilloscope waveforms 4. mathematical ratios

The power output from a transmitter increases from 1 watt to 2 watts. This is a DB increase of:
1. 1 db 2. 3 db 3. 6 db 4. 30 db
