(i) Determine the cutoff frequency of the$$T{E_{11}}$$ mode.
(ii) Determine the frequency at which this / mode has an attenuation of $$3\,\pi $$ nepers/m.

For a microprocessor system using I/O-mapped I/O the following statement(s) is NOT true

A microprocessor with a 16-bit address bus is used in a linear memory selection configuration (i.e. Address bus lines are directly used as chip selects of memory chips) with 4 memory chips. The maximum addressable memory space is

In register index addressing mode the effective address is given by
