A common TV jammer (глушилка) circuit is designed to block infrared (IR) signals from a remote control by flooding the receiver with noise. This is most effectively achieved using a configured as an astable multivibrator to generate a continuous 38 kHz signal. Core Principle
Most TV remotes communicate via IR light pulses at a carrier frequency of 38 kHz (though some vary between 32 kHz and 40 kHz). A jammer sends out constant 38 kHz pulses, causing the TV’s receiver to read a constant "HIGH" or "ONE" logic state. This overlaps and drowns out the specific pulsed data codes sent by the remote. glushilki tv shema
