CONNECTION OF COMPUTING FREQUENCY-MODULATED DEMODULATOR WITH HIGH SLOPE

摘要

The connection can be used with frequency demodulation of signals independently on the size of their carrier frequency. The connection solves the problem of linear demodulation in such a way that it removes the present disadvantage of the computing FM demodulator, i.e. low steepness of conversion with high carrier frequencies. The merit of the connection lies in the fact that the input of the linear converter current - voltage and at the simultaneously controlled current source, which is controlled via the integration amplifier by the voltage from the output of the converter current - voltage, are connected with the output of the linear converter frequency - current.<IMAGE>
