find the bandwidth of the circuit shown in figure below?

In a baseband communications link, frequencies upto 2500Hz are used for signaling. Using a raised cosine pulse with 60% excess bandwidth and for no inter-symbol interference, the maximum possible signaling rate in symbols per second is:

A GaAS device is doped with a donor concentration of 3 x 10¹⁵ cm^-3 . For the device to operate properly , the intrinsic carrier concentration must remain less than 5 % of total concentration . The maximum temperature on that the device may operate is

For the signal given below

If sampling rate = 10³ samples / sec dind the optimum value of step size

A quartz piezoelectric crystal having a thickness of 1.5 mm and volage sensitivity of 0.05 V-m/N is subjected to a pressure of 2 MN/m². The permittivity of the quartz is 40.6 × 10^–12 F/m. The output voltage is

Statement (I):

On-chip Cache memory is used for temporary storage of commonly used code/data copied from the main memory.

Statement (II):

Provision of Cache memory eliminates the need for the processor to off the chip to access the main memory thus improving the processor performance.
