A) We have an amplifier that amplifies a 1 kHz signal from a detector. The load for this amplifier can be modelled as a 50 k resistor. The amplifier output has a large amount of 500 KHz noise. We need to reduce the amplitud of noise by a factor of 10. Design a first-order passive filter which car be/placed between the amplifier and the load. Calculate the value of signal attenuation due to the filter? B) A telephone line carries both voice band (0-4 kHz) and data band (2.5/kHz to 1 MHz). Design a filter that let the data band through and rejects the voice band. The filter must meet the following specifications: For the dat band, the change in transfer function should be at most 1 dB.
