Aband-limited signal m(t) of 3 khz bandwidth is sampled at rate of
33⅓ % higher than the nyquist rate. the maximum allowable error in the
sample amplitude (i. e., the maximum quantization error) is 0.5% of the peak
amplitude mp
. assume binary encoding. find the minimum bandwidth of the
channel to transmit the encoded binary signal.

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
