Duty cycle vs hertz

Did you know?

WebBoth are measured in terms of cycle per second, or hertz. The PRF is normally much lower than the frequency. For instance, a typical World War II radar like the Type 7 GCI radar had a basic carrier frequency of 209 MHz (209 million cycles per second) and a PRF of 300 or 500 pulses per second. WebFrequency is expressed in cycles per second, or Hz. Duty cycle is percent of time that the signal stays at high level. It is typically expressed as the percentage of the period. As an …

WebDuty cycle is the ratio of time a load or circuit is ON to the time a load or circuit is OFF. A load that is turned ON and OFF several times per second has a duty cycle. Why do this? … WebDuty Cycle. When the signal is high, we call this "on time". To describe the amount of "on time" , we use the concept of duty cycle. Duty cycle is measured in percentage.
