Design an FDM signal set consisting of five voice channels, each in the frequency range 300 Hz to 3400 Hz. The multiplexed composite is to be made up of inverted sidebands and is to occupy the spectral region form 30 kHz to 50 kHz. (i) Draw the composite spectrum indicating individual spectrum and guard band frequency locations. (ii) Draw a block diagram showing the heterodyning and filtering details and the required local oscillator values.

Design an RC high-pass filter that rejects 60.0 - Hz line noise from a circuit used in a detector. Your criteria are reduction of the amplitude of the line noise by a factor of $1000 .$ and total impedance at high frequencies of $2.00 \mathrm{k} \Omega$. a) What components will you use? b) What is the frequency range of the signals that will be passed with at least $90.0 \%$ of their amplitude?
