Abstract
A pulse-width demodulator and information storage device including a data ocessing clocking system and an independent data readout and recorder control clocking system. The data input may comprise a pair of words for each data collection cycle. By means of an index signal, which is synchronized with the data input, the device distinguished between each word of the data pair being processed. The device converts each pulse-width modulated word into a digital format and stores each pair of words alternately in one of a pair of shift registers. The readout is alternately from the other of the pair of shift registers to the recorder on command from the recorder.
Claims10
A pulse-width demodulator and information storage device for processing a series of at least a first pair and a second pair of pulse-width modulated words comprising:
- a. first data means for receiving said pairs of pulse-width modulated words;
- b. a first clocking means responsive to the output of said first means for generating first clock signal pulses that are synchronized with the pulses of said pairs of pulse width modulated words;
- c. a first shift register;
- d. a second shift register;
- e. second means responsive to the output of said first data means and to output of said first clocking means for alternately shifting said first pair of words into said first shift register and then shifting said second pair of words into said second shift register;
- and
- d. third means for alternately shifting said first pair of words out of said first shift register and then shifting said second pair of words out of said second shift register.
The device of claim6 including:
- a. fifth and sixth AND gates;
- b. a second clocking means;
- c. the output of said second clocking means connected to one input of said fifth AND gate and to one input of said sixth AND gate;
- and
- d. the second output of said second flip-flop device being connected to the other input of said fifth AND gate and the first output of said second flip-flop device being connected to the other input of said sixth AND gate.
