For the following questions answer them individually
Two ideal quantizers A and B have following specifications :
A: 5 bit Quantizer with input dynamic range of -1V to +1V with Q1 as quantization noise power
B: 8 bit Quantizer with input dynamic range of -0.5V to +0.5V with Q2 as quantization noise power.
Then Q1/Q2 will be
A UART is configured to transmit 8 bit data, 1 start bit and 1 stop bit. The serial data output is observed on oscilloscope, which looks like a square wave with frequency of 9600 Hz. Whatis the baud rate and transmitted data?
A transmission line having characteristic impedance of 50ohms has to deliver 1OKW power at 100KHz to a load. Maximum permissible value of rms current anywhere along the line is 20A. Whatis the maximum VSWR that can be tolerated on this line?
The decoding circuit shown in the figure is has been used to generate active low chip select signal of memory interfaced to 8 bit microprocessor with 16 bit address bus. What is address range and size of memory?
If the waveguide cross-section of a square waveguide with TE11 propagation mode isgradually deformed into a circle, then the corresponding circular waveguide mode will be:
The flux in a magnetic coreis sinusoidally varying at 200 Hz. The maximum flux density is 2 Tesla and eddy current loss is 15 W.If the frequency is raised to 400 Hz and maximum flux density reduced to 1 Tesla, the eddy current loss will
