Testing systems that include digital signal processing systems
First Claim
1. A method of testing hardware, the method comprising:
- activating, by a control system during testing of one or more analog hardware elements included in a signal path of an electronic device, testing software of a digital signal processing system that is included in the signal path of the electronic device, the testing software being configured to cause the digital signal processing system to perform linear operations with respect to signals that traverse the signal path;
deactivating, by the control system during the testing of the one or more analog hardware elements, operating software of the digital signal processing system, the operating software being configured to cause the digital signal processing system to perform non-linear operations with respect to signals that traverse the signal path; and
activating, by the control system, the operating software and deactivating the testing software in response to the testing of the one or more analog hardware elements finishing.

Abstract
According to one or more aspects of the present disclosure, operations may include activating testing software of a digital signal processing system instead of activating operating software of the digital signal processing system. The testing software may be configured to, while activated, perform linear operations with respect to signals that traverse the signal path. The operating software may be configured to, while activated, perform non-linear operations with respect to signals that traverse the signal path. The testing software may be activated during testing of one or more hardware elements of the signal path that are configured to perform analog operations on signals that traverse the signal path.

9. A method of testing hardware of a system that performs digital signal processing, the method comprising:
-
activating, by a control system during testing of one or more first analog hardware elements included in a first signal path of an electronic device, first linear testing software of a first digital signal processing system included in the first signal path; deactivating, by the control system during the testing of the one or more first analog hardware elements, first non-linear operating software of the first digital signal processing system; and muting, by the control system during the testing of the one or more first analog hardware elements, a second digital signal processing system included in a second signal path of the electronic device, the muting nulls signals that traverse the second signal path and the second digital signal processing system being configured to perform operations with respect to signals that traverse the second signal path. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system comprising:
-
a signal path; one or more analog hardware elements included in the signal path; a digital signal processing system included in the signal path; one or more non-transitory computer-readable media configured to store one or more instructions; and one or more processors communicatively coupled to the one or more computer-readable media and configured to, in response to executing the one or more instructions, cause performance of operations comprising; activating, during testing of the one or more analog hardware elements, linear testing software of the digital signal processing system; and deactivating, during the testing of the one or more analog hardware elements, non-linear operating software of the digital signal processing system. - View Dependent Claims (17, 18, 19, 20)
