Question 1. (25 points) Search on the terms dielectric resonator, mechanical filter, and ceramic filter. Look at manufacturer websites and examine specific products. Print out data sheets as need to determine filter types and specifications. Answer the following questions: 1. Name one manufacturer for each of the types of filters you studied. 2. What kinds of filters did you find? (LPF, HPF, BPF, etc.) 3. What frequency range does each type of filter cover? 4. Define insertion loss and give typical loss factors for each filter type. 5. What are typical input and output impedances for each filter type? Question 2. (25 points) Perform Internet searches on the terms AM, AM applications, SSB, SSB-SC (suppressed carrier), or similar terms. Look for the major uses of AM and SSB, and the services, which use AM/SSB. Answer the following questions. Keep searching until all questions are answered. Questions: 1. Name at least five places where AM is still used. 2. Name at least three places where SSB is used. 3. What is the main benefit of SSB? 4. What is the main disadvantage of SSB? 5. In what frequency range is SSB normally used.

A filter is a circuit designed to pass AC signals in some frequency range and to attenuate others. Common filters include low-pass filters, which allow low-frequency signals to pass but attenuate high frequencies; high-pass filters, which do the opposite; and band-pass filters, which pass a range of frequencies while attenuating signals with frequencies outside the band. Filters are widely used in electronics. Applications include tone and equalizer controls in audio equipment; filters to separate nearby frequencies at cell phone towers; and filters to eliminate unwanted electrical noise in biomedical instruments such as electrocardiographs. A simple design for an $R C$ filter is shown in Fig. 28.27 FIGURE CANT COPY The circuit of Fig. 28.27 a. exhibits resonance at frequency $\omega=1 / R C$ b. exhibits resonance at frequency $\omega=1 / \sqrt{R C}$ c. produces an output voltage whose frequency differs from that of the input. d. produces an output voltage whose phase differs from that of the input.
