The frequency of the waveform is defined as the number of cycles occurring in each second of time. The unit of frequency, cycles per second, is often abbreviated cps. For example, Figure 1.29 shows three sinusoidal waveforms, each having a different frequency. In Figure 1.29a, only one ...

Frequency is measured in units of Hertz (Hz), or cycles per second: 1 megahertz (MHz) = 106 Hz, and 1 gigahertz (GHz) = 109 Hz. In the three decades from when one of the authors' families bought an Apple II+ computer to the present time of writing, microprocessor clock frequencies ...

It is assumed that the carrier frequency is high enough so that many cycles occur during the burst interval. While the group delay, step, and impulse curves cannot be used directly to predict the distortion to the waveform caused by the filter, they are a useful figure of merit when used ...
* Based on internal testing using corrosion chambers, Q-FOG and CCT-1100. The Complex Cycle Test (CCT) includes cycles of spray (for 2 hours at 35°C), dry (for 4 hours at 60°C with 30% Relative Humidity) and damp (for 2 hours at 50°C with 95% Relative Humidity) condi...
The oscillator 14 might operate at about 400 k. c. so that when rectified tone is applied to the reactance tube-the frequency of the oscillator might shift from 399.96875 k. c. for "space" to 400.03125 k. c. for "mark." This would give a frequency shift of 621/2 cycles per second...
