- Stephen Woodward.. Many of these “Sound Card Scopes” are quite capable, providing input scaling, triggering and timebase options, frequency analysis, data file storage, and built-in signal generators. But even the best software app can go only ...Feb 15, 2022
- Jim McLucas.. IC 1 ’s input-offset voltage and input-bias currents. R 1 , R 4 , and C 1 provide a small amount of gain boost as the frequency increases to 25 MHz, and C 5 then begins to roll off the gain. Figure 1. This precision peak detector ...Sep 14, 2022
- Jim McLucas.. is a simple frequency doubler circuit that produces a square wave output with a precise 50 percent duty cycle. There are ...Sep 7, 2022
- Mehmet Efe Ozbek.. power consumption and clear, penetrating sound. An external driver or a self-driven circuit that oscillates at the resonant frequency of the piezoelectric element can drive these buzzers. A piezoelectric element produces the maximum ...Nov 17, 2022
- Enrique Vargas Raúl Gregor Sergio Toral Vicente González.. basically the same, but this one can drive a 2.3-nF capacitive load at frequencies as high as 500 kHz. Figure 1. This high-frequency, high-voltage amplifier can drive the capacitive load from a PVDF (polyvinylidene-fluoride) ...Dec 2, 2022
- Stephen Woodward.. 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 ...Feb 9, 2023
- Jim Williams.. 1 is a micropower voltage-to-frequency converter. A 0 V to 5 V input produces a 0 kHz to 10 kHz output with a linearity of 0.05%. Gain drift ...Mar 2, 2023
- Eliane Garnier Francis Rodes Salma Alozade.. 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 ...Aug 3, 2023
- Jim McLucas.. 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 ...Aug 24, 2023
- Stephen Woodward.. 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 ...Oct 10, 2023
