Interference suppressor Electrical functional diagram

SYNTHESIS OF FUNCTIONAL CIRCUIT OF JAMMER The circuit includes elements such as bandpass filter, amplifier, adjustable amplifier, differential amplifier, adder, multiplier, diode bridge, low-pass filter. The bandpass filter (BF) is designed to extract signals whose frequency lies within a certain band w01 < w < w02. At the same time, it almost without attenuation passes the signals lying in this band and attenuates signals whose frequencies lie outside the bandwidth. They can be broadband and narrowband. An amplifier is an element of a control system designed to amplify an input signal to a level sufficient to activate an actuator (or recording elements), due to the energy of an auxiliary source, or due to a decrease in other characteristics of the input signal (the term "signal" hereinafter means any phenomenon (or process) whose characteristics need to be increased). In adjustable amplifiers, it is possible to control the gain (output signal level) in order to prevent overloading of the terminal device (or output stages of the CU), create comfortable conditions for listening to audio programs (in audio frequency amplifiers), calibrating measuring amplifiers, etc. Differential amplifier is an electronic amplifier with two inputs, the output of which is equal to the difference in input voltages multiplied by a constant. It is used when it is necessary to isolate a small voltage difference against the background of a significant in-phase component. The output of the differential amplifier may be either single phase or differential. DU is used when weak signals can be lost against the background of noise. The RD at the receiving end restores the original signal. Adders are combined digital devices that perform arithmetic (as opposed to logical) addition and subtraction of numbers. They have independent values ​ ​ and are the core of circuits when building arithmetic LUNs that implement several different operations that are part of all processors. In adder there is addition of output voltages of channels. Multiplier is intended for carrying out mathematical operation of multiplication of two signals. It has an output value proportional to the product of two input independent quantities. Diode bridge is designed for conversion (rectification) of alternating current into pulsating one. This rectification is called half-period. The diode bridge is one of the most important parts of electronic devices connected to electric current. In simple terms, a diode bridge is one of the solutions on which the process of AC rectification is based. In our world, most electrical appliances require direct current, not alternating current. Therefore, we need to transform the variable into a constant. A low-pass filter (LPF) is one of the types of analog or electronic filters that efficiently passes the frequency spectrum of a signal below a certain frequency (cutoff frequency), and reduces (suppressing) the frequency of the signal above this frequency. The device must have an amplitude characteristic, while it must monitor the maximum densities of the interference probability distribution. The characteristic can be formed as follows: three comparators are used, the response thresholds of two of which correspond to the maximum density of the interference probability distribution. The trigger threshold of the third is zero. Elements 1-21 are involved in the formation of this characteristic. Band-pass filter and amplifier (1, 2) are used for preliminary amplification and required frequency of signal selection. For rough adjustment of controlled comparators (10, 11), open control circuit consisting of amplifier, diode bridge and LPF (4, 8, 12) is used. Fine tuning circuit is tracking circuit and consists of amplifier, multiplier and LPF (18, 20, 21).Circuit signals are summed in adder (15), amplified in amplifier (14) and transmitted to control inputs of adjusted comparators.
