PRODUCTION DATA
The band-pass filter provides amplification and filtering without external components. The lower cut-off frequency is approximately a factor of 2 lower than the average signal frequency of 130 kHz, the higher cut-off frequency is approximately a factor of 2 higher than 130 kHz.
The limiter converts the analog sine-wave signal to a digital signal. The limiter provides a hysteresis depending on the minimal amplitude of its input signal. The duty cycle of its digital output signal is between 40% and 60%. The band-pass filter and the limiter together have a high gain of at least 1000.
