Question

1. If a signal is 1000Hz, how long is a cycle?

Answers: 10 ms, 33ms, 1 ms, or 1000 ms?

2. A complex signal is composed of three simple signals. At 50 ms, the amplitude of Simple-Signal1 is 10; the amplitude of Simple-Signal2 is 5; and the amplitude of Simple-Signal3 is 11. What is the amplitude of the complex signal at 50 ms?

Answers: There isn't enough info, 15, 26, or 50?

3. A complex signal is composed of two simple signals. Below is the amplitude of the two simple signals at different time periods. What is the value of the y-axis on a waveform of the complex signal at 20 ms?

Answers: 5 ms, 20 ms, 250 ms, or 50 ms?

5. Which of the following has frequency on the y-axis and time on the x-axis?

Answers: Spectrogram, Spectrum, Waveform, or Hz?
