Definitions
- the aforementioned IR receiver circuit may also be desirable for the aforementioned IR receiver circuit to be a component of a so-called extender to amplify the received infrared signal and in the amplified-and in particular modulated-form to spend again.
- the object of the invention is to provide an IR receiver circuit of the type mentioned, which makes it possible in a simple way, in particular even in the presence of an interference field, to provide the aforementioned functions.
- the pulse sequence gensignal only used to generate the additional output signal when the receipt of a burst of an infrared signal is determined at the same time due to the output signal of the demodulator.
- the pulse sequence signal thus extracted can then be used for the purposes explained above, for example as an extender function.
- the logic circuit can be designed as an analog logic circuit, wherein in the said additional output signal, the pulse train signal of the comparator modulated onto the carrier signal of the infrared signal and is substantially sinusoidal.
- the additional output signal is in this case analog or only quasi-digital.
- said logic circuit may comprise a transistor which is deliberately not overdriven.
- the pulse train signal generated by the comparator is used exclusively for the logic operation with the output signal of the demodulator. In other words, said comparator can be used exclusively for generating the explained additional output signal.
- the use of the comparator 411 to generate the pulse train signal supplied to the AND gate 413 has the advantage that existing IR receiver circuits, the i.d.R. are formed as Halbleiterbauemem- te, can be used.
