A transmitter transmits an AM sinal with a carrier frequncy of 1530kHz. When an inexpensive radio receiver (which has a poor selectivity in its RF-stage bandpass filter) is tuned to 1530kHz, the signal is heard loud and clear. This same signal is also heard (not strongly) at another dial setting.State, with reasons, at which frequency you will hear this station. The IF frequency is 455kHz.
If you are asked to build an 8 bit odd parity generator/ checker with the output ERROR=1. when there is a 1 bit error, which type of gates, XOR or XNOR is simpler to use Explain
If the motor is driving a load whose torque requirement remains constant at 3Nm, independent of speed. Calculate the armature voltage Va to be applied in steady state, if the load to be driven at 1500RPM.
The amplifier is connected to the handset antenna which has an impedance of 35 + j10 at one unspecified operating frequency. Find the inductive reactance and capacitive reactance needed to match the transmitter output to the antenna
Design a circuit that lets exactly one full negative pulse (from an input train of pulses) pass through to the output, after a button is pushed.
A magnetic material fills the half-space z 0) is free space. The per-meability of free space is mu_0 and the permeability of the magnetic material is 5 mu_0. The magnetic flux density in the magnetic material is B2= 10 ax+ 15 ay-20 az
How do you create a C-style string. Give examples. How do you input or output a C-style string. What kinds of tools are available to work with C-style strings. Show some examples of using those tools.
he sensor to be used has a transfer function of ? Q volts, where Q is in gal/min, and an output impedance of 2.0 k?. Tests show that the output of the sensor has 60 Hz noise of 0.8 V rms. Design a signal-conditioning system, including noise filter..
Considering an ideal transformer with impedance on the secondary, neglecting the winding resistances, leakage inductances and the core loss. N1/N2=3 For a voltage of 120V (rms) at a frequency of 60 Hz applied to winding 1
The bit energy to one-sided noise density at a PCM receiver input is 30 dB. Referring to the figure above, determine the approximate detected S/N ratio (in dB) for 8-bit BPSK with a matched filter detector.
The respective resistance measurements (from the first bar) are 11.1 kW, 12.1 kW, and 14.5 kW.Find the a) material resistivity and b) contact resistivity, then c) restate the material resistivity as a sheet resistivity.
