Consider the front end of the receiver that is shown in the block diagram in Figure P-14.19. The received signal power at the input to the first amplifier is -113 dBm, and the received noise power spectral density is -175 dBm/Hz. The bandpass filter has a bandwidth of 10 MHz, and gains and noise figures are as shown. Determine the signal-to-noise ratio Ps/Pn at the input to the demodulator.
Using a text editor, create a file that is between 5,000 and 6,000 bytes long on a newly formatted floppy disk. calculate the file directory and fat entries for the type of disk used, and check your calculations using absolute sector program
Consider a signal g(t) which is the time-reversed real signal f(t), so g(t) = f(-t). Let g(t) have Fourier series coecients, cn. How are the Fourier series coefficients, cn and dn related
Considering that the only parameters known are the input line-to-line voltage of 415V rms (f=50Hz), the firing angle (a= degrees) and the overlap angle (b=15degrees), calculate the Power Factor as seen from the input AC
To meet the signal-to-noise ratio of the receiver, the received power must be at least 10 µ W. Assuming the two antennas are aligned for maximum reception to each other, including being polarization matched, what should the gain (in dB) of the tra..
