A 128 kbps PCM signal is generated from an audio signal sampled using a 16-bitADC. How many samples are generated per second? What is the SNR

A 128 kbps PCM signal is generated from an audio signal sampled using a 16-bitADC. How many samples are generated per second? What is the SNR forquantizing noise? What is the normalized step size for the ADC? What is thenormalized resolution for the ADC?
