Project description
Develop an intermediate frequency path of a communication receiver. IF frequency is 70 MHz. 1 MHz bandwidth. The gain is adjusted in the range of 20-40 dB digital code. The accuracy of the gain factor is 1 dB. Weakening of the signal during the disruption of 3 MHz from the IF is 40 dB. Nonlinearity of the ACH in the bandwidth is 3 dB.
Requires: functional circuit, principled electrical circuit with all denominations and explanations and a list of elements in accordance. With ESCD.
A task for a course project. Therefore, the scheme should be as simple as possible and correspond only to the above characteristics.
