What else can I help you with?
If the input frequency to a full wave rectifier is 400Hz what is the ripple frequency?
twice the frequency that is rectified.
If the frequency spectrum of a signal has a bandwidth of 500 Hz with the highest frequency at 600 Hz what should be the sampling rate?
The Nyquist Therorem states that the lowest sampling rate has to be equil to or greather than 2 times the highest frequency. Therefore the sampling rate should be 400Hz or more.
What is a 400 hertz generator mean?
It's a generator that creates 400hz AC signals, instead of 50 or 60hz. 400hz is often used on ships, because the equipment (generators, transformers) can be made much smaller.
What is the frequency produced by a 4-pole generator rotating at 3600 rpm?
f=P*N/120 f=Frequency in Hz P= No. of Poles N=Rotor Speed in Revolution per minute(rpm) for P=4 and N=3600, f comes out to be 120 Hz. So frequency of voltage produced is 120 Hz. But this is not practical. Generally 4-Pole generator has N=1500rpm(for 50 Hz) or 1800rpm for 60 Hz. Two pole generator can have N=3600rpm(f=60Hz). The most practical situation is generator having N=3600Hz with 2 Poles. Hope It will be helpful!!!
What is the main advantage of DC over AC for aircraft electrical power systems?
It doesn't have to be rectified. That's the ONLY advantage; the electrical systems in all but the smallest planes are 400Hz AC systems.
If the input frequency to a full wave rectifier is 400Hz what is the ripple frequency?
twice the frequency that is rectified.
What is the period for an AC waveform with a frequency of 400Hz?
The period for an AC waveform with a frequency of 400Hz is ( \frac{1}{400} = 0.0025 ) seconds or 2.5 milliseconds. Period is the inverse of frequency, so it represents the time taken for one complete cycle of the waveform at that frequency.
If a bass guitar has a frequency of 400Hz what frequency would your eardrum vibrate at?
Any frequency/note played by said bass guitar
What is the fourth harmonic of a fundamental frequency of 400 Hz?
1600HZ 400HZ x 4
How can you make a static inverter keeping the frequency at 400Hz accurate?
You can make your static inverter to maintain 400Hz by means of compare the generated frequency of your inverter with the reference buildin frequency generator which is called local oscillator or multivibrator which is fixed at 400 Hz. If your inverter generate frequency grater or less than 400Hz then the comparison between the reference frequency and the generate frequency will produce the error signal to reduce or increase the generated frequence and send it out. This is the principle operation of the Electrical Power Generation System. Post this answer by : tassana.e@thaiairways.com
How do Frequency and Pitch differ?
Although the response of the human ear varies from individual to individual and also changes with age, the range of hearing is 20 Hz with maximum sensitivity between 200-400hz. Pitch refers to the sensation of increase or decrease of frequency.
What is the frequency of a note one octave higher than 200Hz?
The frequency of a note one octave higher than 200Hz is 400Hz. In music, an octave represents a doubling of the frequency.
What is the frequency range of speech?
A Deep male voice could start as low as 80Hz. A prepubescent child ranges from 150 to 400Hz
In a 3-phase high voltage star-star connection 140KVA transformer and load phase voltage is 115v and frequency is 400hz what is the total load current?
Maximum load current on a 140KVA, three phase transformer when the output voltage is 115 v phase to phase is: 140kva / sqrt (3) / 115 = 703 Amps. frequency does not matter here.
What is the speed of a wave if its wavelength is 0.02meters its frequencyis 400hz?
If you multiply the wavelength (in meters) and the frequency (in Hertz), you will get the speed of the wave (in meters per second).
What is the wavelength of 400Hz?
The wavelength of a 400 Hz wave in air is approximately 0.85 meters. This can be calculated using the formula: wavelength = speed of sound / frequency.
If the frequency spectrum of a signal has a bandwidth of 500 Hz with the highest frequency at 600 Hz what should be the sampling rate?
The Nyquist Therorem states that the lowest sampling rate has to be equil to or greather than 2 times the highest frequency. Therefore the sampling rate should be 400Hz or more.
