NJM2299 Series
Wave Shaping Circuit for Demodulated FSK Signal

  • Description

    The NJM2299 is a low - current wave shaping circuit to change a noisy or weak demodulated FSK signal to the original digital signal. Low bit-rate demodulated signal is especially suitable for input signal. Our unique circuit features excellent response characteristics for intermittent operation. It may be also helpful to prevent the read-error of the data including continuous '00' or 'FF' data.
