At 1 mW input signal, the amplifier connected to a mixer will have an output of 1 W. At maximum power transfer, determine the a. input power in dBm b. output power in dBu ANS. O dBm, 60 dBu

Please answer in typing format please ASAP for the Please I will like it please I appreciate your support and I

Design an transistor amplifier with a total voltage gain of 40. The signal source has a 10 kohm impedance. The load is 5 kohms. Please show all work.

Identify the types of power amplifiers used to amplify low-level AM signals. (Check all that apply.) Class C amplifier Class D amplifier Class A amplifier Class B amplifier Linear amplifier

I need ans..... in 10 minutes please help me    If the input voltage of an amplifier is 3.46 V rms and its voltage gain is 80, what is the rms output voltage? Also find the gain in dB?

A boost converter has an input voltage Vb=5V. The average load current is lo=0.5A. The switching frequency is 25 kHz. Suppose that a regulator is added (L=.15 mH and C=0.22 mF) and that the current is continuous. If the average output voltage is Vo =15V, then the critical values of L and C for the considered boost converter are equal to: Select one: O a. 0.133mH and 0.88UF O b.0.0665 mH and 0.44UF c. 0.133mH and 0.44UF d. None of these

4) Below is the small signal model of a multistage amplifier. Using this model, write the equationsthat you would need to determine the voltagegain. IMPORTANT: You only need to providethe equations that you would need to determinethe voltage gain. You DO NOT need to combine and simplify the equationsto determine a final expression for the voltagegain. Vin Vo Vb vo1 Rb R13 Vbe1 Vbe2 'e gm 1 Vbe1 gm 2 Vbe2 Rc2 Rc1 Re
