SHOT Noise
because noise usually changes the amplitude not frequency.
The "kissing noise" of a transformer, often referred to as the "buzz" or "hum," typically occurs at the frequency of the alternating current (AC) supply, which is usually 50 Hz or 60 Hz, depending on the region. This noise is generated due to the magnetostriction effect in the core material, causing it to expand and contract as the magnetic field fluctuates. In some cases, higher-frequency harmonics can also contribute to the noise, but the fundamental frequency remains at the power line frequency.
the frequency difference between the transmitter and the receiver without any noise or distortion
quantisation noise decrease and quantization density remain same.
AS FREQUENCY INCREASE THE BANDWIDTH INCREASE. AS WE KNOW NOISE HAVE LARGER BANDWIDTH. SO ITS AFFECT HIGH FREQUENCY SIGNAL. BUT LOW FREQUENCY SIGNAL HAVE LOW BANDWIDTH SO IT IS LESS AFFECTED BY NOISE. ALSO WE KNOW QUALITY FACTOR= CUTOFF FREQUENCY / BANDWIDTH. SO AS FREQUENCY INCREASE B.W. INCREASE SO QUALITY DEGRADE. CUTOFF FREQUNCY AND THE TERM FREQUENCY (USED HERE) IS DIFFERENT. CUTTOFF FREQUNCY IS USED IN FILTER. PRABIR KUMAR SETHY prabirsethy.05@gmail.com
A big noise is a person of great importance or influence in a position or situation.
noise are assumed frequency independent......
because noise usually changes the amplitude not frequency.
Noise frequency refers to the rate at which sound waves oscillate, measured in hertz (Hz). In the context of sound, it describes the pitch of the noise, with higher frequencies producing higher pitches and lower frequencies resulting in deeper sounds. Noise can encompass a wide range of frequencies, from low-frequency rumbling (like thunder) to high-frequency sounds (like a whistle). Understanding noise frequency is important in fields like acoustics, audio engineering, and environmental noise control.
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.
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.

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.....
