What types of noise are frequency independent?
White noise and pink noise are examples of noise that are frequency independent. White noise has equal intensity across all frequencies, while pink noise has equal power in each octave.
Why is amplitude modulation susceptible to noise but not frequency modulation?
because noise usually changes the amplitude not frequency.
Which noise becomes a great importance at high frequency?
SHOT Noise
What happens to noise when frequency of the wave decreases?
When the frequency of the wave decreases, the pitch of the noise decreases, making it sound lower. The noise may also become more rhythmic or repetitive as the frequency decreases. Additionally, lower frequency noises can travel further distances and penetrate obstacles more effectively.
How would you eliminate the high frequency noise in integrator?
To eliminate high frequency noise in an integrator, you can use a low-pass filter at the input of the integrator to block high frequency signals. You can also increase the integration time constant to filter out high frequency noise. Additionally, using a precision op-amp with good common-mode rejection can help reduce noise in the integrator circuit.
Which type of noise has sound at every frequency within the range of human hearing?
White noise
If sampling frequency doubles then quantization noise?
reduces
Why Fm is more immune to noise than AM?
b/c information lies in frequency... while in AM information lies in amplitude and noise effects the amplitude more as compare to frequency....... there for.....
What is coarse frequency offset?
the frequency difference between the transmitter and the receiver without any noise or distortion
How does noise cancellation in headphones work?
Noise cancellation headphones work by blocking high-frequency sound waves and erasing lower-frequency sound waves. This can occur due to their ability to mimic incoming noise in order to produce their own sound waves.
What are the two main causes of vibration?
noise and frequency are made a vibration
Sampling frequency doubles then quantization noise?
quantisation noise decrease and quantization density remain same.
