The probe band limited signal with fmax= 1Mhz was transmitted during the time T0=2 minutes.a) Find the maximum number of samples (N) that can be sent through the channel during T0 without losing of information.b) Find the sample rate (samples/s)c) If PCM is used to transmit the probe signal in digital format (with μ = 255), how much bits (K) should be sent through the channel during T0 if the S/N ratio required is 20 dB.d) if PCM is used to transmit the probe signal in digital format (with μ = 255), find the bit rate (bits/s) for S/N ratio 20 dB.
Suppose it is known that a 5MHz transducer axis makes an angle of 30 degrees relative to the direction of motion of blood in a vessel. If the Doppler frequency is measured to be +500Hz, what is the velocity of the blood
How does noise affect the measurement signals in analog and digital data lines. Why is one signal sensitive to noise and the other one is not
Are the systems stable For functions above, determine the steady state response for a step input. Determine the natural frequency , and the damping ratio and sketch the step response.
(a)using 4 rectangles find the area of the region bounded by f(x)=x^2 +1, the axis from x=0 to x=2,(b) solve part (a) using n rectangles and the limit process as n -> infinity.
A balanced Y-connected load of 100 + j50 Ohm is connected to a balanced three-phase source. If the line current is 42 A and the source supplies 12kw, determine (a) the line voltage; (b) the phase voltage.
A solid spherical conductor of radius a is surrounded by a concentric spherical conducting shell of inner radius b and outer radius c. The region between the conductors, a
A random variable X is normally distributed with mean u = 10 and standard deviation sigma = 1.5. Find the following probabilities: A. P(8 or equal 8.5).
Multiple charges at different locations are said to be in equilibrium if the force acting on any one of them is identical in magnitude and direction to the force acting on any of the others. Suppose we have two negative charges
Suppose we have a 4Kword memory RAM with each word containing 32 bits. How many address bits and how many output bits are needed. Draw the block diagram of a negative edge-triggered JK FF which is asynchronously set by a 1 and asynchronously reset b..
And how long it will take to reach that temperature assuming no heat lost in the process and comments on your results and may research the properties of nichrom wire to determine the resistivity of the wire
According to the Nyquist sampling theorem, faithful reconstruction of an analog signal with a bandwidth of 29 kHz would require a sampling frequency of at least. what is the decimal equivalent of the following binary coded decimal number.
The select inputs are S0-S1, the data inputs are A2-A0, B2-B0, C2-C0, and the data outputs are Y2-Y0. The outputs Y2-Y0 should be equal to A2-A0,B2-B0,C2-C0 for the select-input combinations 00,01,10, respectively and should be zero when the selec..
