• The test signal is periodic in time with period t _ p.
• Two of these lines in each field are reserved for test signals.
• Its test signal constisted of a color test pattern and the network's music.
• Mains power and test signal cabling into the test chamber require high quality filtering.
• Repairers also use signal generators, which provide test signals, and oscilloscopes, which display signals graphically.
• :: Your list of test signals starts with a sinewave, which has a single frequency.
• The tester then applies power to the chip and injects a series of test signals.
• The test signal included classic alternative rock music.
• The reference port will compensate for amplitude variations in the test signal at the measurement plane.
• Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters.
• An alternative method of adjustment was to use a battery-operated buzzer to generate a test signal.
• By measuring the rate of motion of the test signal the offset between frequencies can be determined.
• Thus, any spurious signals caused by the test signal or distortion will not degrade the signal-to-noise ratio.
• The station took to the air with music and a test signal in the spring of 2002.
• The network analyzer needs a test signal, and a signal generator or signal source will provide one.
• But if the first test signals trouble, yearly follow-ups can help monitor both the condition and the treatment.
