.. design idea with a 555 analog timer that can generate an arbitrary triangle/sawtooth with its waveshape and frequency controlled by pots. If you could assemble the list of all the oscillators that have been designed ...
.. that prevent entry of a cable or a probe. The circuit in Figure 1 reduces noise effects because its VFC (voltage-to-frequency converter) produces a PPM (pulse-position-modulated) output signal, V OUT , that integrates, or ...
.. will operate, if this is an appropriate spec for the circuit. Mentally, I give the circuit a low score if the operating frequency range is, in my opinion, limited. My nagging thought was “can the operating frequency range for ...
.. 50:50 square waves, thus slicing and dicing the time axis into equal segments. He’s also often included a wide-range frequency doubler functions: Convert any signal to exactly 50% duty cycle ( Ref. 1 ) Frequency doubler with 50 ...
.. design idea (DI) does exactly that by using asynchronous RS-232 to power and count pulses from a simple 10-kHz voltage-to-frequency converter (VFC). Getting only one bit of info from each 10-bit serial character may seem inefficient ...
.. the noise, the greater the size, expense, and difficulty of the filter design. Power supplies that operate at a fixed frequency have their largest EMI emission at this fundamental, fixed frequency. Emissions also occur at multiples ...
.. designed the circuit in Figure 1 as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation. Figure 1. A digital frequency divider circuit that ...
.. 65,536 conversion results in real time, thus providing an increase in signal-to-noise ratio (SNR). Figure 2. The combined frequency response of filter plus ADC is flat out to a 10-kHz input. The inputs of this circuit are driven ...
.. by simply connecting a tuned circuit to its input. It turned out that it was possible to create a simple tuned radio frequency (TRF) receiver by implementing the two features of the LM386 mentioned earlier and using a tuned ...
