Abstract:
A device for generating a pulsed electrical signal for use in biomedical applications, said device comprising:first means for producing asymmetric oscillations, said first oscillator means producing a logic signal having first oscillations when said device is in electrical connection with a power source;second means for producing asymmetric oscillations, said second oscillator means producing second oscillations when said device is in electrical connection with a power source;circuit means for combining said first and second oscillations to produce an output waveform, said circuit means operating to switch said second oscillator ""on"" or ""off"" depending on a state of said logic signal;output means for transmitting said output waveform to electrodes for stimulating biological tissue; andmeans for adjusting a frequency of said output waveform, said frequency-adjusting means electrically connected to said output means, said frequency-adjusting means varying said frequency in approximately logarithmic fashion.
