the -3 dB frequency for low pass Butterworth filter is 2.5 kHz. The stop band begins at 3.8 kHz, with an attention of 35 dB. Determine the minimum order of the filter if the sampling rate is 8 kHz
a) What is the minimum sampling frequency b) Specify the number of uniform quantization steps needed and the channel null bandwidth required, assuming that the peak signal-to-noise ratio at the receiver output needs to be at least 30 dB
A temperature sensor has a static transfer function of 0.15 mV/C° and a time constant of 3.3 s. If a step change of 22° to 50° C is applied at t=0, find the output voltage at 0.5 s from t=0s to t=10s. What is the indicated temperature at these tim..
Consider an LTI(linear,time-invariant) system with input x(t) and output y(t). Suppose you know(measure) the step response, tha is , for x(t) =u(t), you know that y(t) = 2e^(-0.5t)*u(t). Find the output for the following different inputs
resistor: a volt-ohmmeter with an internal impedance of 1000 Ω/V and an EVM with an impedance of 11 MΩ. Calculate the voltage indicated by each of these devices.
In the question below only focus on the parameter or parameters that are relevant to the particular property you are being asked about in the particular question. If you need to constrain a parameter to satisfy the stated criterion.
Determine the settings Z1, Z2 & Z3 for the relay at B12.
Locate and specify an appropriate sensor if it is to operate at 120 vac as an input to a PLC. Create the ladder diagram program to accomplish the specified control.
Two amplifiers(CS) connected in cascade. The input voltage to the first stage has a source voltage Vsig and Rsig= 100KOhm. Rv=10KOhm AND IS CONNECTED TO THE DRAIN OF THE SECOND STAGE. BOTH TRANSISTORS HAVE Id=.25mA and Vov=.25V
a. Design a 3 bit combinational circuit 2's complimenter. (the circuit generates the 2's compliment of the input 3-bit binary number). [Show all work leading to the circuit implementation]
1) in a swamped common-emiter BJT amplifier, as shown below, if Vcc =12 V, R1 =8.2 kohm, R2=10 kohm, Rc = 500 ohm, Re= 1 kohm, Vbe = 0.7 V, and B =100, what is the transistor`s emitter current
Explain the structure and nature of the ionosphere with reference to daily, seasonal and long-term changes and explain the modes of propagation of radio waves of different frequencies
Suppose you have a line charge and a point charge in space. A point charge of 16nC is located at Q(2,3,5) in free space, and a unifor line charge of 5nC/m is at the intersection of the planes x=2 and y=4. If the potential at the origin is 100V, fi..
