Assume the IF amplifier in Figure 5-44 has an IF transformer with a primary 26 inductance...
Apply the concept of Multistage O0000 O0000 The amplifier in Figure 5-36 is a low-power andio amplifier. The transfomer is step-down impedance-matching transformer designed to give a reflected reaistance in the primary of 1000 2 when the load is 8 2 (such as the speaker).. The dc resistance of the primary winding is 66 2 and B= 150 (a) Compute Va and the Ig for the transistor (b) Compote A A, and power delivered to the load when the input...
