need home in greenville sc can i get this phone in my andrews, sc.29510, i was told that the gov. assistance phone is not in my town. i applied but no reply need home phone Do I quafly For Home Phone i need a home phone can you help me to get me a phone what s the cheapest home phone service for disabled whats the cheapest home phone service for disabled
It could be delivered by ground mail, but that option seems exceptional, so most likely, it would be by plane. That would be First Class Mail.
My Mom has passed away in April of 1999, and I found 2 life insurance policies from January 5th, 1942. They were under the name of Penny Coutsos Policy # 28734 for $250.00 and then Penny Tucker, Policy # 76326 for $250.00. Is there any information that you can give me on these 2 policies? Thank you Howard Tucker 941-743-6506 xtrmgrph@Comcast.net
The difference between double side band long carrier (DSB LC) and double side band short carrier (DSB SC) is the is how the amplitude modulation (AM) is referenced in the carrier wave.
in DSB-SC since carrier is suppressed,hence power consumption is reduced and nominal.The power in the modulated signal is contained in all four sidebands.The bandwidth of the DSB-SC signal is double that of the message signal, that is, BWDSB-SC =2B (Hz).How many sidebands? There's only two; upper and lower.
Vestigial Sideband Transmission is used for the transmission of Television signals.Because the video signals need a large transmission bandwidth if transmitted using DSB-FC or DSB-SC techniques.

-Carrier not available in receiver -Envelope detection not possible
in SSB-SC only one side band of AM s/g is sent frm Transmitter instead of both sideband and carrier in that of DSB-FC(DSB-FC consist of upper side band ,lower side band both conveying same information i.e. mirror image of each other and original carrier i.e. after the process of modeulation carrier is also present in DSF-FC s/g). thus DSB-FC = USB+LSB+Cariier hence total power in DSB-FC= cariier pow+ usb pow+lsb pow SSB-SC = either USB or lsb toatal pow= pow in single side band 1.using SSB-Sc power is saved. 2.Bandwith is reduced 3. noise immunity is more.
Applications:- Analogue TV systems: to transmit color information.- For transmitting stereo information in FM sound broadcast at VHF- One important application of DSB is the transmission of color information in a TV signal.- CB radio- TV broadcasting- Air traffic control radios- Garage door opens keyless remotes- DSB-SC is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave.- DSB-SC used in stereo transmission of FM radio.- Two way radio communications.
The advantages of DSB-SC are that power consumption is nominal, the power from the signal can be contained in four sidebands, and the bandwidth is double the amount in the signal.

linear receiver. The more difficult case of a nonlinear receiver is deferred to Section 2.12. Consider the case of DSB-SC modulation Figure 2.36 shows the model of a DSB-SC receiver using a coherent detector. The use of coherent detection requires multiplication
WE CAN use the balanced modulator & also the double balanced modulator(DBM) THANKS. ASMA
