Explain Quantizing Analog Signals?
A common analog-to-digital conversion pipeline contains a spectrum limiter (a simple low-pass or bandpass filter), a sample and hold circuit, a quantizer, and a digitizer. Quantization inevitably introduces errors, although errors can be decreased by:
a) Increasing the number of quantization levels
b) Introducing non-uniform quantization
Q. Explain the different types of probes used in cathode Ray Oscilloscope (CRO). Sol. probes: The probe performs the very important function of connecting the test circuit
Serial Input output Ports For serial input and output there are two pins in 8085 microprocessor
Q. Determine voltage and current gains for the CE BJT amplifier shown in Figure with the following parameters: R 1 = 30,000, R 2 = 9000 ,R C = 750 ,R E = 250 , R L = 1000
What is the function of the time-base generator as used in an oscilloscope
HILDA ( Output) It is called hold acknowledge signals it is active high i e it goes high when microprocessor receives HOLD signal.
Q. Consider Figure of the weighted differencing amplifier. Let R 3 = R 1 and R 4 = R 2 . Determine the input resistance between terminals a and b of the circuit.
