The voltage gain shall be 50, equivalent to 34dB, and the input sensitivity shall be 1.05 Vrms. The signal to noise ratio over the range of 20 Hz to 20 kHz shall exceed 100 dB unweighted. IHF damping factor shall exceed 200. The amplifier chassis shall occupy two rack spaces, with ...
Iref has the shape of a rectified sinewave and it's amplitude is such that it maintains the output dc voltage at a reference level Vref, against variation in load and fluctuation in line voltage. The sensed digitized inductor current Iin is compared with the reference current Iref. The ...
The ratio of peak-to-average absolute voltage in a simple unmodulated carrier is about 1.6:1. When two equal-amplitude nonrelated carriers are summed, however, the relationship is not as simple. Figure 12.20 shows three possible waveforms resulting from the simple addition of two sine waves whe...
The voltage and the voltage representation of a current can be measured with the ADC of the Arduino by using appropriate input circuitry for scaling the measured quantities down to within the 0-5V compliant voltage range of the ADC. The provided solution uses a simple method for scaling the me...
sine wave high frequency voltage is applied to the electrode 3 while a resonance circuit is formed of the electrode 3 and an electrostatic capacity detection circuit 6 and the change in the electrostatic capacity of the electrode 3 due to the flow of the gas-liquid two-phase stream is ...

1. Connect the output terminals of the Function Generator to a 1kΩ Resistance. 2. Turn on the Function Generator and use the oscilloscope to observe the voltage drop across the 1kΩ resistance. 3. Select the sine wave output option of the Function Generator ...
As the rectified sine wave voltage and current approaches the cusp at zero, the inductor current becomes discontinuous. Discontinuous operation can occur over a substantial portion of the line cycle, especially when line current is low at high line voltage and/or low power input. With peak ...
