Unformatted text preview: H ( F ) = j sin(2 πF ) • H ( F ) = 8 e j 2 πF 8-5 e-j 2 πF Problem 2. Draw the phase and magnitude of the following ﬁlters and classify them (lowpass, highpass, or bandpass): • H ( f ) = 1 1+ jf • H ( f ) = jf 1+ jf Problem 3. m ( t ) is a signal with bandwidth of 10 Hz . Double sideband modulation is per-formed to generate the signal g ( t ) given as g ( t ) = m ( t )sin(100 πt ) Then g ( t ) is given as an input to the system shown in the following ﬁgure where the ideal lowpass ﬁlter has a bandwidth of 10 Hz . Find y ( t ). 1...
