2b The result of reproduction from the magnetic recording medium, which enters the input ish: not 14, passes through the band-pass filter 16 and the amplifier-limiter G on the trigger I mitta 2, which forms it into a pulsed form. The Schmitt trigger 2 through differentiation element 3 starts the standby generator 4, acting on the integrator 15 and the low-pass filter 5.
