For the ADC, when the word length increases by 1 bit, the SNR during quantization increases by about 6db.
举一反三
- During ADC conversion, a sinusoidal signal with amplitude being 1 is input and the ADC operates at full range. When the quantization word length b = 8bits(one symbol bit and seven data bits), the SNR of the quantization process is approximately A: 44dB B: 50dB C: 56dB D: 62dB
- For nonuniform quantizer, such as μ-law and A-law, the SNR for low-level signals increases at the expense of the SNR for high-level signals.
- Which type of cost always increases immediately when output increases?
- During the current year, the assets of The Big Dial increase by $132,000, and the liabilities increase by $80,000. As a result, owners' equity A: decreases by $52,000 during the year. B: increases by $52,000 during the year. C: increases by $212,000 during the year. D: is $52,000 at the end of the year.
- When the Fed makes an open-market sale， it：（ ） A: increases the money multiplier (m). B: increases the currency-deposit ratio (cr). C: decreases the monetary base (B). D: increases the monetary base (B).
