What computer parts or functions are described by Hz?
monitor Refreash rate of the monitor or of memory use CPS which is Hz.
After a vigorous exercise an athlete found his heart rate to be 150 beats per minute A what is the frequency F of his heartbeat in Hz and B what is the period of his heartbeat?
150 per minute is a perfectly good expression for frequency.The period is the reciprocal of frequency = 1/150 = 0.00667 minute (rounded)If you're more accustomed and more comfortable with frequency in Hz and period in seconds, then:Frequency = 150 / min = 150 / (60 sec) = 2.5 HzPeriod = (60 sec) / 150 = 0.4 second
What is power freqency of ct?
The power frequency of a current transformer (CT) typically refers to the frequency of the alternating current (AC) that the CT is designed to measure, which is commonly 50 Hz or 60 Hz, depending on the regional power system standards. CTs are used to step down high currents to a lower, manageable level for measurement and protection purposes. The design and performance of a CT are optimized for these frequencies to ensure accurate readings and minimal distortion.
What artist painted a Victorian sleeping woman with cherubs around her playing musical instruments with people dancing in the top left hand corner of the painting with initials HZ in the bottom left?
Hans Zatzka, an Austrian artist. He also painted under several other names including Hans Zabateri.
What is the difference between a decibel and frequency?
Hertz (Hz) means the unit of cycles per second (1/T). It has to do with the frequency. Decibel (dB) is a logarithmic unit of measurement that expresses the magnitude of a physical quantity.Since it is a ratio of two quantities with the same unit, it is a dimensionless unit. Both have nothing to do with each other. It is totally different, like cars and bananas.
What is the sampling rate of music CDs?
44,100 Hz or 44.1 kHz
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 the unit of measurement of the sampling rate when recording sound waves?
The sampling rate is expressed in units of either "samples per second" or "Hertz (Hz)".
What is the sampling rate in Hz?
Sampling rate is a defining characterstic of any digital signal. In other words, it refers to how frequently the analog signal is measured during the sampling process. Compact disks are recorded at a sampling rate of 44.1 kHz.
What is the sampling rate for PCM if the Frequency ranges from 1000 to 4000 Hz?
>8000hz
What uis the sampling rate for PCM if the Frequency ranges from 1000 to 4000 Hz?
As we know that the sampling rate is two times of the highest frequency (Nyquist theorm) Sampling rate=2 Nyquist fs=8000hz/8khz
What unit of measure is used to express the sampling rate of a sound card?
hertz Hz
What is the sampling rate in HZ of a music CD?
Standard audio CDs use a sample rate of 44.1 kHz, each sample has 16-bit resolution and there are two audio channels. 44,100 x 16 x 2 = 1,411,200 bits/s = 1,411 kbps. For comparison, the highest bit rate for MP3 is 320 kbps.
What is sampling rate in sound?
The sampling rate is the number of samples taken from a continuous signal over a period of time (typically measured per second - Sa/s or Samples per Second). The Nyquist - Shannon Sample Theorem states that a sample rate should be double the highest recorded frequency. Since the range of human hearing is 20Hz - 20,000 Hz, the minimum sample rate should be 40,000 Hz. CD format sample rates are 44.1kHz for this reason as well as other technical reasons.
State and prove the sampling theorem?
If the signal is bandwidth to the fm Hz means signal which has no frequency higher than fm can be recovered completely from set of sample taken at the rate
What is Nyquist frequency?
The Nyquist frequency is defined as half of the sampling rate of a discrete signal processing system. It represents the highest frequency that can be accurately represented when sampling a continuous signal without introducing aliasing. According to the Nyquist-Shannon sampling theorem, to avoid distortion, a signal must be sampled at least twice the highest frequency present in the signal. For example, if a signal is sampled at 1000 Hz, the Nyquist frequency would be 500 Hz.
What is the difference between sample size and sampling rate?
Rate refers to frequency, while size refers to the amount. Thus, Sampling Rate is measured in Hertz (number of times per second a sample is taken), and Sampling Size is measured in Bits (number of binary digits of information taken at a single time). Thus, if you Sample at 10 Hz/8 bits, that means you take 8 bits of information, 10 times per second.
