Question

Why does the shape of a periodic waveforms often change when it is amplified? The amplifier amplifies noise and the signal which distorts the signals shape. There are four sources of noise that get amplified: Johnson noise, shot noise, EM pickup and pink noise. The amplified signal has a different shape than the input signal The amplitude of a signal increases when it is amplified. Periodic signals have many frequency components, and amplifiers often have a gain that depends on frequency, so all components are not amplified the same amount. Amplifiers are often built from substandard components which do not perform uniformly at different frequencies. What does 'RMS" represent RMS = Routing Management System is the technique to route analog information into digital storage RMS " = "Records Management System, " digitizing a signal requires a great deal of memory that must be managed, typically with a "first in" "first out" protocol RMS = Rate Monitor Slews, " it specifies the requirement on the output driver on an amplifier to follow a signal the amplifier is monitoring It is a measure of the average magnitude of the signal

Explanation / Answer

For questn1 the amplitude of signal increase s when it is amplified amplifier never change s frequency of the input signal which is to be amplified... Amplifier changes only amplitude and phase but not frequency....And for 2nd questn RMS means Root mean square value of the signal that is measuring average magnitude of the signal...
