Abstract:
A receiver section of a telephone comprising:a demodulator unit for receiving and demodulating an input signal; a processor unit for processing the demodulated input signal, said processor unit including balanced outputs; a speaker; an amplifier unit including balanced inputs coupled to the balanced outputs of said processor unit, and balanced outputs coupled to said speaker for providing an amplified input signal thereto; and a switch circuit for selectively coupling the balanced outputs of said processor unit to the balanced inputs of said amplifier unit based upon a closing control signal; and a control unit for generating the closing control signal for closing said switch circuit according to a predetermined delay with respect to a power up signal for preventing disturbances in said processor unit, due to transients of the power up signal, from appearing on a processed input signal being applied through said switch circuit to said amplifier unit.
