The common mode rejection ratio of an ideal amplifier is infinity.
In FM, the effect of noise is more on higher frequencies when compared with low frequencies. Therefore in order to have high signal-to-noise ratio(low noise), the high frequencies are amplified at the transmitter side and for compensation deemphasis(decreasing the amplitude of those boosted frequencies ) is done at receiver.
No, Pre-emphasis is done before modulation. We need it to do for improving the SNR ratio of the signals of higher frequencies. Actually this boosting of weaker higher frequencies of data signals. (Asked question is a sort of trap question usually asked in viva or interview.... ;) )
dc characteristics:- 1.input off set voltage, 2. input bias current, Ac characteristics:- 1, commen mode rejection ratio, 2. slew rate
A: Most op amp feature a 90 Db noise ratio rejection. For a 741c it varies from 70 to 90 Db ideally the bigger the number the better.
common mode rejection ratio is defined as ratio of differential voltage gain to common mode voltage gain Common mode rejection ratio is the ability of the circuit to reject common entries like noise.
The common mode rejection ratio of an ideal amplifier is infinity.
Ratio between the frequencies of the speakers
CMRR is common mode rejection ratio. it is the ratio of Differential gain to common mode gain. CMRR=Ad/Ac
a high common mode rejection ratio, high impedance
Two notes sounded together, whose frequencies are in the ratio of small integers.
In FM, the effect of noise is more on higher frequencies when compared with low frequencies. Therefore in order to have high signal-to-noise ratio(low noise), the high frequencies are amplified at the transmitter side and for compensation deemphasis(decreasing the amplitude of those boosted frequencies ) is done at receiver.
The larger the whole number corresponding to the ratio of frequencies of combined tones is, the more dissonant they sound together. Example: Smallest possible whole-number ratio of 2 frequencies = 2/1 = 2 . . . the "octave". Larger ratios sound more dissonant.
CMR is Common Mode Rejection, and it is a measure of how well a balanced amplifier rejects a common mode signal, i.e. one that appears on both signal lines, such as one that would be induced by noise. The CMRR, Common Mode Rejection Ratio is the powers of the differential gain over the common mode gain, expressed in decibels.
The musical interval between two notes depends on the ratio of their frequencies. An octave is a ratio of 2:1 and, in equal temperament comprises 12 equal semitones, which therefore have a ratio of 21/12.
Musical frequencies and notes are determined by the specific vibrations they produce. These vibrations create patterns that our brains recognize as harmonious and pleasing. The mathematical ratios between frequencies, like the 2:1 ratio of an octave, are what make certain notes sound musical. Unlock the healing power of music!

Yes. The different notes represent different frequencies of vibration. One octave is a vibration ratio of 1 : 2. Since each octave has 12 half-notes, and the vibration ratio is the same for each, the vibration ratio from one half-note to the next is 1 : 12th. root of 2, or 1 : 121/12.Yes.
