pulse waveform การใช้

• To ensure accuracy, the sensor should return a steady pulse and / or pulse waveform.
• One unique feature of the envelope is its ability to also control the width of the pulse waveform.
• This is a ramped and pulsed waveform that repeats at the horizontal ( line ) frequency of the display.
• Figure 3a is a simulation of a pulse waveform recorded by receivers P _ 0 and P _ 1.
• :: : : The " pulsed waveform " you describe would be variations in the power and ground wires of the USB cable.
• The central tone-generating component of the instrument is a set of 6 digitally controlled oscillators capable of producing sawtooth and square / pulse waveforms.
• Certain aspects of the electric signal are unique to each species, especially a combination of the pulse waveform, duration, amplitude, phase and frequency.
• If the original emitted pulse waveform is s ( t ), then the detected signal ( neglecting noise, attenuation, and distortion, and wideband corrections ) will be:
• The last two of these, the frequency spectrum and the pulse waveform, are interrelated via the Fourier transform and may be seen as two different ways of describing the same pulse.
• Thus, selecting the pulse waveform together with any other waveform causes every bit on the DAC to partially mix, and the loudness of the waveform is affected by the state of the pulse.
• Fortunately, the volume level could be mostly restored with either a hardware modification ( biasing the audio-in pin ), or more commonly a software trick involving using the Pulse waveform to intentionally recreate the required bias.
• :8038 can generate triangle, sine and square 555 can only generate pulse waveforms [ http : / / www . national . com / pf / LM / LM555 . html-- Light current 09 : 11, 21 October 2006 ( UTC)
• If we consider a pulse waveform f ( t ), with period T, low value y _ \ text { min }, a high value y _ \ text { max } and a duty cycle D ( see figure 1 ), the average value of the waveform is given by:
• The top bit drives whether the XOR circuit inverts the accumulator value seen by the DAC . Thus, enabling triangle and sawtooth simultaneously causes adjacent accumulator bits in the DAC input to mix . ( The XOR circuit does not come to play because it is always disabled whenever the sawtooth waveform is selected . ) The pulse waveform is built by joining all the DAC bits together via a long strip of polysilicon, connected to the pulse control logic that digitally compares current accumulator value to the pulse width value.
