EEL 3552 Experiment 2

please answer all thanks !

Number 22

a) Briefly explain Continuous signals, Discrete Time signal and Digital Signals. Include diagrams/waveforms and examples of each type of signals. b) Compare the Continuous and digital signals by mentioning at least two advantages and disadvantages of both types of signals

Fundamentals of Mixed Signals and Sensors  Topic: ADC DAC Solve for the output of the DAC in figure below if the waveforms representing a sequence of 4-bit numbers in figure below are applied to the inputs. Input D0 is the least significant bit (LSB).   Reverse the input waveforms to the DAC in the figure (D3 to D0, D2 to D1, D1 to D2, D0 to D3) and determine the output.

The serial data-input waveform (Data in) and data-select inputs (S0 and S1) are shown in Figure Determine the data-output waveforms from D0 through D3.

Do it soon , now ( course” Digital Electronics Technique

Sequential Circuits, Thank you in advance for your answer.

1) If the given waveforms are the inputs of AND gate draw the output waveform. a 1 C 2) The above given waveforms are the inputs of OR gate draw the output waveform. 3) Waveform a is the input of a NOT gate draw the output waveform.

d) Design (Find the values of the R₁, R2, and C₁) an astable multivibrator circuit to have an output waveform as shown below in the figure (tH = 375µs and t₁ = 125µs). (Assume C₁ = C₂ and R₁ # R₂) and determine the frequency of oscillation and the duty cycle. R1: R2 C1 Q Vcc 4 555 5 C2 10nF I 8 1 3L -OVO tH = 375.0us tL = 125.0us

SOLVE CAREFULLY!! Please Write Clearly and Box the final Answer Hint : Enter your answer to the 3rd nearest decimal place in seconds.

Listen A 12 bit DAC has a lower reference voltage of OV and an upper reference voltage of 3.0V What is the output voltage for a code of Ox74B? Round the answer to 2 decimal places. a) 1.37V Ob) 1.50V c) 1.60V O d) 1.12V

For the plant represented by signal flow graphs in Figure , determine the controllability andobservability of the systems.
