Measuring the Frequency of an Input Square Wave Using the TMS320F240 EVMDavid Figoli
MEASURING DEVICE FOR EFFECTIVE VALUE OF FUNDAMENTAL WAVE OF DISTORTED WAVE Output signals of the FF 13 and the phase shifter 15 are brought to a frequency division by the FF 14 and 17, respectively. In this way, when the sine wave signal iA of a prescribed amplitude is outputted from the...
systems that use a wide range of frequencies (ionosondes) for monitoring the state of the ionosphere; equipment for the measurement of ionizing radiation; a system to monitor magnetic and wave activity; a dual-frequency transmitter of radio signals at frequencies of 150 [...] daccess-ods...
A method for measuring the frequency of continuous wave and wide pulse RF signals using multi-purpose, commercial-off-the-shelf test devices, such as an RF signal down converter, a digitizer and a signal processor. The method is based on digitizing the RF signals and dividing the digitized da...
effect,this article has established one new liquid surface wave frequency measuring technique.At the experiment has carried on the survey to various frequencies liquid surface wave propagation velocity,fitted the data,and has conducted the research to between the wave velocity and the wave length ...
If a time is elapsed on and after this time while the circuit 10 is held to this state, the high frequency signal revolves succeedingly in this feedback loop to obtain a wave form V'B(t). Therefore, the high frequency signal is obtained at every delay times tau, 2tau-ntau and the...
I'm trying to improve upon some existing code I had that uses the method of using the input square wave to externally clock one of the MCU's timers, and then gating it with a second 1Hz timer, where I simply take the first timer's counter value as the frequency (well, also some ...
SOLUTION: For the brain wave measuring device and the brain wave measuring method of this invention, a light stimulation signal generation part 7 generating control signals for emitting the light stimulation having a stimulation frequency of a frequency band of brain waves under consideration, the ...
