Standard audio CDs use a sample rate of 44.1 kHz, each sample has 16-bit resolution and there are two audio channels. 44,100 x 16 x 2 = 1,411,200 bits/s = 1,411 kbps. For comparison, the highest bit rate for MP3 is 320 kbps.

Unlike the dynamics of the early baroque, Classical music dynamics tended to be a little more diverse, yet without the passion of the Romantic era. There was the range, from the pianissimo to the fortissimo but music of the early Classical era lacked the dramatic and sudden changes characteristic of later Classical composers such as Beethoven, who led into the Romantic.
The most popular tuning for guitar is(from highest to lowest string): e' = 329.6 Hz, b = 246.9 Hz, g = 196.0 Hz, d = 146.8 Hz, A = 110.0 Hz, E = 82.4 Hz.
lowest pitch: 246 Hz- B3 (B below "middle C" on a piano) 349 Hz- F4 (F above "middle C") highest pitch: 880 Hz- A5 (A one octave above "middle C")

The Nyquist Therorem states that the lowest sampling rate has to be equil to or greather than 2 times the highest frequency. Therefore the sampling rate should be 400Hz or more.
The sampling rate is expressed in units of either "samples per second" or "Hertz (Hz)".
Sampling rate is a defining characterstic of any digital signal. In other words, it refers to how frequently the analog signal is measured during the sampling process. Compact disks are recorded at a sampling rate of 44.1 kHz.

As we know that the sampling rate is two times of the highest frequency (Nyquist theorm) Sampling rate=2 Nyquist fs=8000hz/8khz

The sampling rate is the number of samples taken from a continuous signal over a period of time (typically measured per second - Sa/s or Samples per Second). The Nyquist - Shannon Sample Theorem states that a sample rate should be double the highest recorded frequency. Since the range of human hearing is 20Hz - 20,000 Hz, the minimum sample rate should be 40,000 Hz. CD format sample rates are 44.1kHz for this reason as well as other technical reasons.
If the signal is bandwidth to the fm Hz means signal which has no frequency higher than fm can be recovered completely from set of sample taken at the rate
Rate refers to frequency, while size refers to the amount. Thus, Sampling Rate is measured in Hertz (number of times per second a sample is taken), and Sampling Size is measured in Bits (number of binary digits of information taken at a single time). Thus, if you Sample at 10 Hz/8 bits, that means you take 8 bits of information, 10 times per second.
I would like to sample the signal Xa(t) =1+cos(10 *pi*t) using sampling frequency fs=8 Hz. How can I calculate this? ANSWER: Your signal has a frequency component of 5hz (from the equation: 2*pi*f*t = 10*pi*t, therefore f=5). The Nyquist rate for this signal (the minimum sampling rate required to reconstruct the signal) is then 10Hz, and even at that rate the amplitude of the sampled signal will be reduced unless you can somehow synchronize the sampling with the peaks/troughs of the cosine signal. If you sample at 8Hz you will not be able to reconstruct the signal at all.
