What is the minimum number of bits necessary for a digital audio converter to have 24 dB of headroom and a signal-to-noise ratio of at least 48 dB?
Added by Andre R.
Step 1
Step 1: The headroom in dB can be calculated using the formula: Headroom (dB) = 20 * log10(2^n), where n is the number of bits. Show more…

In the compact disk (CD) digital audio system, an analog signal is digitized so that the ratio of the peak-signal power to the peak-quantization noise power is at least 96 dB. The sampling rate is 44.1 kilosamples/s. (a) How many quantization levels of the analog signal are needed for (S/N_q)peak = 96 dB? (b) How many bits per sample are needed for the number of levels found in part (a)? (c) What is the data rate?

If a PCM signal has a maximum PCM decimal code value of +31 and a -31, how many bits were used for coding?

Consider an audio signal with spectral components limited to the frequency band of 300 to 3300 Hz. A PCM signal is generated with a sampling rate of 8000 samples/s. The required output signal-to-quantizing-noise ratio is 30 dB. (a) What is the minimum number of uniform quantizing levels needed, and what is the minimum number of bits per sample needed? (b) Calculate the minimum system bandwidth required.
