Open the CIPO recordAbstract From the Canadian patent
A multistage amplifier having an automatically programmable gain is disclosed in which the amplifier gain is incremented in binary steps to a desired level. Each amplifier stage is switchable between a first and second gain in a binary sequence such that the four digit output of a sixteen bit counter will increment the total amplifier gain in sixteen binary steps. A readback and decoding circuit for reading magnetic tape is also disclosed in which the signal amplitude of data read fro the magnetic tape is compared to a reference voltage which corresponds to the data readback clipping level. Only amplified data which exceeds the predetermined clipping level is gated out of the circuit for …
