FREQUENCY TREBLER Russian patent published in 2017 - IPC H03B19/14 

FIELD: radio engineering, communication.

SUBSTANCE: in a frequency trembler, containing a divider 1, an adder 2, a comparator 3, a single vibrator 4, and a sampling-storage device 5, whose first input is connected to the input bus of a frequency trember and the second input to the output of a single vibrator 4, whose input is connected to the comparator output 3. The output of divider is connected to the first input of adder 3, the output of which is connected to the output bus of frequency trembler, the exponentiation block 6 and the differentiating unit 7 whose output is connected to the inverting input of comparator 3, the non-inverting input of which is connected to the common bus, are additionally introduced. The input bus of frequency trembler is connected to the input of differentiating unit 7, the second input of adder 2, and the first input of the exponentiation block 6, the first and second outputs of which are connected respectively to the first and second inputs of analog divider 1, and the second input of exponentiation block 6 is connected to the output of sampling-storage device 5.

EFFECT: ability to vary the frequency and amplitude of the input signal over a wide range to obtain harmonic output signal, whose frequency is three times higher than the frequency of the input source.
