<p>A quasi-analog reconstruction of an amplitude and frequency varying analog input signal is produced as a staircase waveform, each step voltage of which is generated by utilizing the binary bits of a corresponding codeword of a PCM signal derived from the analog input signal. …<??>In order to achieve optimum resolution, the binary bits of each PCM codeword are considered as C in number, of which an A number are major bits and a B number are minor bits; the A bits being converted to a (2<A>-1) number of discrete decimal bits, each of which controls the switching to and from a series voltage summation line (20) of a discrete voltage Vc …<CHEM>… where Vmax is substantially the peak voltage amplitude to be provided in the reconstructed signal. Individual ones of the B bits directly control the individual switching to and from the summation line of discrete voltages of unequal magnitudes declining in one-half voltage increments from Vc/2 to @@.…… </p> |
