For the Op-Amp circuit shown in the figure, V₀ is

For the BJT circuit shown, assume that the $$\beta $$ of the transistor is very large and V_BE = 0.7 V. The mode of operation of the BJT is

In a transconductance amplifier , it is desirable to have

In a GSM system, 8 channels can co-exist in 200 KHz bandwidth using TDMA. A GSM based cellular operator is allocated 5 MHz bandwidth. Assuming a frequency reuse factor of 1/5, i. e. a five-cell repeat pattern,, the maximum number of simultaneous channels that can exist in one cell is
