.. bias resistor R 4 , because of single-supply operation). The negatron portion of the circuit uses op amp IC 2 . The output frequency, f, of the modulator without the negatron is a function of the time constant Figure 1. The modulator ...
.. an engine with only one LED as an indicator. The measurement of the number of revolutions usually involves sensors with a frequency output proportional to the number of revolutions. The circuit compares the frequency output of such a ...
.. you use a function generator, you may occasionally require a sine-wave output at a higher frequency than the generator can provide. If your function generator also produces a triangle-wave output, you ...
.. This can be achieved, for example, by using an IC such as Mixed Signal Integration’s Mixed Signal MiXer and Very High frequency Filter ( MSMXVHF ) to baseband, while the Mixed Signal Low powered Spectrum Analyzer (MSLSA) provides ...
.. 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 ...
.. 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 ...
.. 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 ...
.. 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) ...
