A periodic composite signal with a bandwidth of 3000 Hz,is composed of two sine waves. First one has a frequency of 100 Hz with a maximum amplitude of 30 V, the second one has a maximum amplitude of 10 V. Draw the bandwidth.
3714We measure the performance of a telephone line (4 KHz of bandwidth). When the signal is 20 V, the noise is 6 mV. What is the maximum data rate supported by this telephone line?
3 24141How much is the signal amplified? and what is the total gain? when a signal is passed through three cascaded amplifiers, each with a 5 dB gain.
3 20820A device is sending out data at the rate of 2000 bps. How long does it take to send out 100 bits? How long does it take to send out a singal character (8 bits)? How long does it take to send a file of 100,000 characters?
1 25325If the bandwidth of the channel is 8 Kbps, How long does it take to send a frame of 200,000 bits out of this device?
4 25774A signal with 300 milliwatts power passes through 10 devices, each with an average noise of 3 microwatts. What is the SNR? What is the SNRdb?
4610A computer monitor has a resolution of 1300 by 1000 pixels. If each pixel uses 1024 colors, how many bits are needed to send the complete contents of a screen?
4 21256I am using windows server 2008 and its working as DHCP server. 100 clients are connected to this server. All clients are accessing Internet.

Hi I have 10+ years of telecom application development experience ( telecom billing product -call control (ISUP/INAP/CAMEL call handling), short message routing application, telecom tools development). I am very strong in C++/Unix , core java and advanced oops design. Recently I have undergone a training in 3G mobile protocol developement. I have very good knowledge about WCDMA, its various layers and gone through 3GPP technical specs. Now I am looking for 3G mobile development opportunities. I am finding very difficult to get it, as I don't have the relevant experiences on 3G development. Please advice me on this to enter into mobile protocol development.
