Base station transmit a signal to a User. The User is 1Km away from the BS.It has a LOS connection.
If the last reflected signal travel around 1.5km to reach the User. Find the corresponding delay spread of the system. (c = 3 x ). The distortion caused by multipath transmission can be partly corrected by a tapped delay line equalizer. Show that if α « 1, the distortion in the multipath system in figure (a) can be approximately corrected if the received signal is passed through the tapped delay line equalizer shown in next figure.

Q3.
1. State the 3 Major Types of signal distortions. And state the frequency domain conditions for
each.
2. State the time domain condition for distotionless transmission.
3. A transmitter send a signal x(t)=A sin(2πfot + ϴ).The channel is the distortion less.
Propagation delay is г to reach to the receiver. Sketch the transmit and receive signals.
Verify the condition for distotionless transmission.
4. A 3000 km repeater system consists of m identical fibber-optic cable sections with
Attenuation 0.5 dB/km and m identical amplifiers. Find the required number of sections
and the gain per amplifier so that Pout = Pin = 5 mW and the input power to each amplifier
is at least 67 pW.

What’s solenoid valve?

A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level

China Lutong Parts Plant is a manufacturer specialist diesel fuel injection system accessory.We have strong technique power, advanced equipment, craft, first class processing test equipment, perfect 

quality assurance system and excellent after services.To face the challenges of globalization of the world economy, we continuously adopt the advanced international processing and testing techniques. 

Our company is a science, industry and trade as a whole, production, supply and marketing of such products of the modern enterprise.

We do provide packing design and manufacturing, for orders greater than 1000 pieces. The packing includes the plastic tube, printed carton packing, and a product label. The pricing of this service depends on the size of your order which will be quoted to you upon your request.

our manufacturing facilities are located in China. We are working with the finest manufacturers in the industry, which comes with a cost. Quality is the key factor for success in any business. Therefore we 

are evaluating our cost of production as a secondary concern. Our primary concern is customer satisfaction which usually driven by quality and competitive pricing.
