Unformatted text preview: what is the image frequency for f0 = 1510 kHz? 3. Let m (t ) = cos ( 2000π t ) − 2 sin ( 2000π t ) , and let c (t ) = 100 cos ( 2π × 10 6 t ) and s (t ) = 100 sin ( 2π × 10 6 t ) . a) Let x1 (t ) be the DSB- SC signal x1 (t ) = m (t ) c (t ) . Find and plot X1 ( f ) . ˆ b) Find mHT (t ) (the Hilbert Transform of m (t ) ). (Hint: Use Fo...
