displays waveforms. It can be used to
measure currents, temperatures, speeds,
and accelerations if they are first
converted to
1. heat
2. light
3. voltages
4. pressures
1-68. The spectrum analyzer is used to display
which of the following quantities?
1. Amplitude within each frequency
component in a circuit
2. Proportions of power within each
frequency component in the spectrum
3. Frequencies produced in a circuit
4. Each of the above
1-69. While testing a semiconductor diode, you
determine that the forward resistance
value is 60 ohms. You should consider
the diode good if the backward resistance
is at least which of the following values?
1. 6 ohms
2. 60 ohms
3. 600 ohms
4. 6,000 ohms
