A filter-method SSB transmitter has the following specs: filter center frequency of 10.7 MHz, filter BW of 3.0 kHz, and carrier oscillator frequency of 10.6985 MHz. The baseband information spectrum is 0.0−3.0 kHz. Draw a simple block diagram of the transmitter and show the spectrum. Which sideband will be passed by the filter?
