You can use a Faraday box which is a box o metal. If you put a radio receiver or a cellular phone inside it will not receive any signal. Cover your cellular with a alufoil.

State sampling theorem?

sampling theorem is defined as , the sampling frequency should be greater than or equal to 2*maximum frequency, and the frequency should be bounded.. i,e fs=2*fmax where fs= sampling frequency


Which racing term is defined as an engine that has failed completely?

A blown engine.


What is the difference between the Butterworth filter and the Chebyshev filter?

The phase linearity of the Butterworth is better than that of the Chebyshev. In other words, the group delay (derivative of phase with respect to frequency) is more constant with respect to frequency. This means that the waveform distortion of the Butterworth is lower. Of course, with a single input frequency, there is no waveform dostortion in either filter. Another point to consider; the Butterworth filter is completely defined mathematically by 2 parameters: Cutoff frequency and number of poles. The Chebyshev filter has a third parameter: Passband Ripple.


What is the nyquist sampling rate and nyquist frequency for frequency f equals 0?

The Nyquist sampling rate is defined as twice the highest frequency present in a signal to avoid aliasing during sampling. For a frequency ( f = 0 ), the Nyquist sampling rate would also be ( 0 ) since there are no oscillations to capture. Consequently, the Nyquist frequency, which is half of the sampling rate, is also ( 0 ). This means that no information can be effectively captured or reconstructed from a signal that is constant (i.e., with a frequency of zero).


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.

How does a decrease in velocity affect the frequency and wavelength of the waves entering the shallow water?

A decrease in velocity of the waves will cause a decrease in frequency and a decrease in wavelength as the waves enter shallow water. This is due to the relationship between velocity, frequency, and wavelength which is defined by the equation: velocity = frequency x wavelength.

What is a signal?

A signal is a function that represents a physical quantity,a function may be defined by two or more variable. e.g a Sinosoidal signal require three parameters to define it completely that are amplitude,frequency and phase.


The of vibration of a wave is defined as that which has the lowest frequency?

The fundamental frequency of a wave is the lowest frequency at which it can vibrate. This frequency corresponds to the first harmonic or the wave's base frequency. It is the most stable and strongest frequency that the wave can produce.

How are the period and the frequency of a wave reletated?

The period of a wave is defined as the time taken by a wave to complete one oscillation. While, the frequency of a wave is defined as the number of oscillations completed by a wave in one second.


What is the SI unit of frequency?

Which term is defined as the exact location where an earthquake occurred?

The term defined as the exact location where an earthquake occurred is the "epicenter." It is the point on the Earth's surface directly above the location where the earthquake's energy is released.


What determines the frequency of an electromagnetic wave?

The frequency of an electromagnetic wave is determined by the speed of light divided by the wavelength of the wave. This relationship is defined by the equation: frequency = speed of light / wavelength.
